• Ultimate x-ray microscope• chemical, structural, strain, domain mapping.• in-situ processes.

• physics and chemistry in the near optical field.• plasmonics.

• nanomagnetism• nanoferroelectricity• oxide MBE, UNCD• STM (e.g, spin-polarized)• novel devices

• computational nanoscience; ‘virtual fab lab’• advanced computing; user friendly code


Enabling Technical Capabilities• Nanosynthesis - ‘bottom-up’

– bio/organic/inorganic synthesis, self-assembly, thin film deposition.

• Nanopatterning - ‘top-down’– lithography (ebeam, FIB, optical), imprint,

pattern transfer (eg, RIE).

• Nanocharacterization– structural, magnetic, electronic, optical,

chemical and dynamical properties.– AFM, MFM, SEM, confocal optical– hard x-ray nanoprobe

• Theory and Simulation– computational materials science– leverage ANL leadership computing.
