Vacuum evaporated dielectrics for use in MOS structures
were studied in this research project. Dielectric
films were deposited on substrates by electron bombardment
evaporation of sapphire and quartz source materials.
These deposited films were studied using infrared spectroscopy,
index of refraction, density, and dielectric constant
measurements. Etching tests were also...
The theoretical characteristics of space-charge-limited
currents in solids are reviewed, and a survey of
suitable dielectric materials and experimental space-charge-limited devices is presented.
The properties of the gold-silicon contact as used
in space-charge-limited devices were experimentally investigated.
It was found that the observed characteristics
could be explained on the basis...
A phase sensitive measurement technique that permits the simultaneous determination
of two independent thermal properties of thin dielectric films is presented. Applying the technique results in a film's thermal diffusivity and effusivity, from which the thermal conductivity and specific heat can be calculated. The technique involves measuring a specimen's front...
Raw material costs and limited material availability and quality have created
significant interest in and opportunities for the application of nondestructive
evaluation techniques to improve wood processing technologies. The incentives come
from the desire to 1) manufacture the highest valued product, 2) conserve the
amount of raw material used, 3)...
