Research Interests and Achievements

Cryogenic High Field Scanning Tunneling Microscopy and Spectroscopy Cryogenic Atomic Force Microscopy and Spectroscopy Iron-based and cuprate superconductors Graphene and Topological insulators Antiferromagnetic metal delafossites Strongly correlated or spin-orbit-coupled materials Analog and digital integrated circuits for advanced instrumentations Precision measurement of electric field Superconducting RF cavity and superconducting wire Low loss transfer method of cryogenic liquids Self-assembly of organic molecules on surfaces Electromechanical switching of molecular chains

1. My main research interests are on the construction of advanced cryogenic high-field scanning probe microscope and its application to the fundamental physics of various unconventional superconductors, strongly correlated systems and topological materials in atomic scale. The key issues addressed so far are: (1) How to build a versatile variable temperature and magnetic field scanning probe microscope for advanced material research (Rev. Sci. Instrum. 88, 103702 (2017), Featured as Journal Cover of October 2017 Issue).

We have built a variable temperature scanning probe microscope (SPM) that covers 4.6 K - 180 K and up to 7 Tesla whose SPM head fits in a 52 mm bore magnet. It features a temperature-controlled sample stage thermally well isolated from the SPM body in good thermal contact with the liquid helium bath. It has a 7-sample-holder storage carousel at liquid helium temperature for systematic studies using multiple samples and field emission targets intended for spin-polarized spectroscopic-imaging scanning tunneling microscopy (STM) study on samples with various compositions and doping conditions. The system is equipped with a UHV sample preparation chamber and mounted on a two-stage vibration isolation system made of a heavy concrete block and a granite table on pneumatic vibration isolators. A quartz resonator (qPlus) based non-contact atomic force microscope (AFM) sensor is used for simultaneous STM/AFM operation for research on samples with highly insulating properties such as strongly underdoped cuprates and strongly correlated electron systems.

(2) How to enhance superconductivity by electron-phonon interaction in heterostructure iron-based superconductor (Phys. Rev. Lett. 119, 107003 (2017)).

A direct microscopic picture of how superconductivity is enhanced by electron-phonon interaction is revealed in FeAs/oxide heterostructure using our high-resolution spectroscopic imaging scanning tunneling microscopy technique. The


9

relationship between particular oxygen vacancies, the superconducting gap and the renormalization of electron band due to the e-ph interaction is revealed for the first time. The result may enable a roadmap to build heterostructure superconductors with significant enhancement of transition temperature taking advantage of electron-phonon interactions.

(3) How to control magnetism and superconductivity by spin-polarized current in frustrated heterostructure superconductor (Phys. Rev. Lett. (2017) (accepted and selected as PRL Editors’ Suggestion), arXiv:1707.01191).

A direct microscopic picture of how to control antiferromagnetism in a frustrated heterostructure iron-based superconductor using spin-polarized and unpolarized current, resulting in controlling superconductivity in nanometer scale, is proposed and demonstrated using our spin-polarized scanning tunneling microscope. The spin-polarized current injection creates an environment that favors plaquette order with unsatisfied nesting condition, turning off the spin-based pairing mechanism. The result may enable a roadmap to build electronic devices controlling superconductivity and magnetism of the conducting channels using spin-polarized current injections.

(4) How to visualize antiferromagnetic phase domain walls and control them with spin-polarized scanning tunneling microscope (arXiv:1608.00884).

A direct microscopic picture of how to visualize the antiferromagnetic domains in iron-based superconductor and how to control them using spin-polarized current is demonstrated for the first time in iron-based superconductor. A detailed analysis using Landau-Lifshitz-Gilbert equation is still in progress.

2. Other active on-going researches based on cryogenic high-field spin-polarized scanning tunneling microscope include: (5) The physics of spin glass state of strongly underdoped cuprates (with Hiroshi Eisaki group in AIST).

Using spin-polarized scanning tunneling microscopy technique, we can visualize how the antiferromagnetism in undoped cuprates develops into spin glass state and finally superconducting state upon gradual doping.

(6) Correlation of magnetism and iron-based superconductivity (with Kee-hoon Kim group in SNU).

Using spin-polarized scanning tunneling microscopy technique, we can visualize how the antiferromagnetism is correlated with iron-based superconductivity.

(7) Weyl metallic states in magnetically doped topological insulators (with Myeong-hwa Jung group at Sogang Univ. and Ki-seok Kim group at Postech).


10

Using spin-polarized scanning tunneling microscopy technique, we can visualize the formation of Weyl metallic state in topological insulator upon doping with magnetic ions.

(8) Charge density wave states and their domain walls in transition metal di-chalcogenides (with Sang-wook Cheong group in Rutgers Univ.).

Using variable temperature scanning tunneling microscopy technique, we can visualize the formation of charge density waves and their domain walls upon cooling down in transition metal di-chalcogenides.

(9) Triangular lattice antiferromagnetism in delafossite nanostructures (with Jun-sung Kim group in Postech).

Frustrated antiferromganetism in triangular atomic lattice in delafossite nanostructures may play unusual role in the large carrier mobility in the metallic atomic layer.

3. My other major research interests are on the construction of advanced cryogenic atomic force microscope and its application to the whole-surface imaging of proteins and other biomolecules. The key issues covered so far are: (10) How to build an atomic force microscope system that allows whole-surface imaging of biomolecules in atomic resolution (US Patent No. 9581617, Korean Patents No. 10-1347557 and 10-1718900, arXiv:1707.03051)

Atomic force microscopy with two independent scanning probes is proposed to achieve whole-surface 3D imaging of proteins and other biomolecules.

(11) How to interpret the supramolecular interaction of organic molecules self-assembled on various surfaces (The Journal of Physical Chemistry C 117, 302 (2013), Applied Surface Science 268, 432 (2013), ChemPhysChem 14, 1177 (2013)).

We visualized the large organic molecules self-assembled on various surfaces and interpreted their formation with the supramolecular interaction models.

4. My other research interests and issues covered so far are: (12) Real-time signal recovery from multi-pole transfer function system (Rev. Sci. Instrum. 88, 085104 (2017))

Based on a rigorous mathematical analysis of how a single-pole transfer function system modifies the input signal, I developed a digital signal processing method with a particular moving average technique that can recover the input signal from the smeared and delayed output signal in real time, significantly reducing the effective time constant. The method can be generalized to multi-pole systems and may open a new market for special low cost digital signal processors to speed up sensors and


11

feedback control systems. (13) Superconducting RF cavity operable under high magnetic field (Phys. Rev. D. 94, 111702 (2016), Korea Patent No. 10-1477989).

In collaboration with the center for axion and precision physics in the institute of basic science, I have developed a specialized large scale superconducting film growth system that can be used to build superconducting cavities for the search of dark-matter candidate particles.

(14) Precision electric field measurement device suitable for muon storage facility (Korea Patent No. 10-1698987).

For collaboration with the J-PARC researchers, I have developed a novel electric-field measurement device that has many orders of magnitude larger sensitivity compared with the preexisting technique based on laser beam deflection on foil electrometer.

(15) Cryogenic analog and digital circuits for general instrumentation (Korea Patent No. 10-1735800),

In order to achieve large signal-to-noise ratio from the electrometer grade amplifier used in cryogenic measurement systems, providing cryogenic temperature environment for the amplifier can be one solution. We solves one of the notable problems of adjusting input offset voltage/current of the cryogenic operational amplifier using a remotely applied control signal.

(16) Low loss transfer methods of cryogenic liquids (US Patent Pending No. 15210810, Korea Patent No. 10-1718904),

A novel method of transferring cryogenic liquid over a long pipeline with minimum thermal loss is proposed. The method can be used to transfer liquid helium in ultra-low temperature facilities and liquid hydrogen for energy industries’ liquefaction and distribution network.

(17) Superconducting wires under magnetic field (Supercond. Sci. Technol. 29, 065004 (2016), Korea Patent No. 10-1690723),

We visualized the vortex motions in superconducting wire in magnetic field and proposed a novel method of producing superconducting wire with regular array of vertex pinning centers to increase the critical current density.

(18) Strain effects on topological insulators (Applied Physics Letters 104 161613 (2014)).

We investigated the correlation between electrical transport and mechanical stress in a topological insulator, Bi2Te3, using conductive probe atomic force microscopy in an ultrahigh vacuum environment.


12

(19) Nanoelectromechanical switching of C60 chains (Carbon 67 48-57 (2014)).

Using first principle calculation, we propose an electromagnetic switching mechanism of fullerene chains realized on epitaxially grown multi-layered C60 molecules using current injection from a scanning tunneling microscope probe.
