FORLWORD
This report was prepared by Hughes Aircraft Company, Culver City,
California, under Contract Number AF 33(615)-2460, a continuation of work
performed under Contract AF 33(615)-1235. The contract was initiated under
Project No. 7381, "Materials Application," Task No. 738103r "Materials
Information Development, Collection and Processing." The work was admin-
istered under the direction of the hir Torce Materials Laboratory, Research
and Technology Division, Air Force Systems Command, Wright-Patterson Air
Force Base, Ohio, with Mr. R. F. Klinger, Project Engineer.
The EPIC Information Analysis Center is a center for the collection, re-
viei and analysis of the scientific and technical literature on the electrical
and electronic properties of materials. Its major function is to evaluate,
compile and publish the experimental data from that literature. Through the
mediu, of a series of publications such as Data Sheets, Special Reports, State-
of-the-Art Peports, Computer Bibliographies, and services including special
otudies, answers to technical inquiries, research support is provided to the
DoD community. EPIC input is primarily from the open literature. A large
number of abstract journals, in addition to about 40 other journals, and the
unclassified report literature are completely searched.
The initial step in the preparation of this data sheet was the retrieval,
by means of a modified coordinate index, of all cadmium oxide literature in
the EPIC file. Bibliographies were also reviewed to ensure the inclusion of
all relevant literature. Those papers containing primary source data were
selected unless only secondary references were available.
If equally valid data are available from several sources, all are given.
Data are relected when considered questionable because of faulty or dubious
iii
measurements, unknown sample composition, or if more reliable and Inclusive data
a: available from another source. Selection of data is based upon evaluation
of that which is most representative, precise, reliable and inclusive over a
wide range of parameters. The addition of new data to a material compilation
rCquire a reappraisal of the reported values. Older data may be deleted in
light of the new data.
Within every property section we have tried to include every available
parameter and range of experimental condition in the literature. Information
on test conditions and sample specification are extracted from the article.
Some slight alterations in units and presentation may be made to facilitate
comparison with other experimental data.
This report consists of the compiled data sheets on cadmium oxide. A full
liot of EPIC publications to date appears at the end of the report.
The author wishes to acknowledge the assistance afforded by Dr. J. J.
Grocnan in reviewing the experimental data, and the contribution of Mr. E.
Schafer in the pre-publication review of the compilation. The supporting
aoir;tance of other members of the EPIC staff, in particular, Mrs. Jean Forest,
Mr. Thomas Lyndon, and Mr. W. S. Hodge, is gratefully acknowledged,

ABSTRACT
These data sheets present a compilation of a wide rnnge of electronic
properties for cadmium oxide. Electrical properties include conductivity,
dielectric constant, Hall coefficient, and mobility. Emission data have
been broken down intu the varied electron and photon emissions which result
from application of electromagnetic energy over a wide spectrum. Energy data
include energy bands, energy gap, and energy levels, as well as effective
mass tables, and work function. The optical properties include absorption,
reflection, and refractive index. Magnetic data are presented, as well as
oev'ral other physical phenomena, such as Debye temperature. Thermsoelectric
and thermomagnetic properties are shown. Each property is compiled over the
widest possible range of parameters including bulk and film form, from ref-
erences obtained in a thorough literature search.
A summary'of crystal structure and phase transitions has been included.
This report has been reviewed and is approved for publication.

Absorption coefficient as a function of photon energy for a cadmium oxide
film prepared at two temperatures. The film was prepared by cathode
sputtering in a nitrogen-oxygen atmosphere, and was then annealed in air
at-5000C.
Evidently the shift in the absorption coefficient on annealing, leads to
a constant value; there is minimum shift during further temperature changes.

These data sheets present a compilation of a wide range of electronicproperties for cadmium oxide. Electrical properties include conductivity,dielectric constant, Hall coefficient, and mobility. Emission data havebeen broken down into the varied electron and photon emissions which resultfrom application of electromagnetic energy over a wide spectrum, -Energy datainclude energy bands, energy gap, and energy levels, as well as effectivemass tables, and work function. The optical properties include absorption,reflection, and refractive index. Magnetic data are presented, as well asseveral other physical phenomena, such as Debye temperature. Thermoelectricand thermomagnetic properties are shown. Each property is compiled over thewidest possible range of parameters including bulk and film formn, fromreferences obtained in a thorough literature search.
A summary of crystal structure and phase transitions has been included.
