In this study, we show that deposited Ge and Si dielectric thin-films can exhibit low microwave losses at single-photon powers and sub-Kelvin temperatures (≈40 mK). This low loss enables their use in a wide range of devices, including coplanar, mic

Device performance and reliability are of concern for devices fabricated on strained Si wafers. For strained Si formed by SiGe crystal growth, defects are of particular interest. We characterized such SiGe samples by pulsed MOS capacitor, gate oxide

Strained silicon germanium carbon (Si1-x-yGexCy or SiGeC) on silicon was oxidized using a novel photooxidation process. The growth rate of the oxide was investigated and found to depend heavily on the germanium and carbon concentrations. MOS capacito

We report on titanium contacts to n-type and p-type Si1−x−yGexCy strained heteroepitaxial layers on (100)Si and material and electrical characterization of n-type and p-type platinum–silicide–germanide contacts to Si1−x−yGexCy strained he

Mobilities in Si1-x-yGex Cy layers were measured using mesa etched Van der Pauw structures for alloy layers with 0 < x < 0.30 and 0 < y < 0.02 and doping levels of 1015 < N < 1018 cm-3. Mobilities in Si1-x-yGex Cy layers with x = 0.27 were found to a

Material and electrical characterization of n-type and p-type Si1-x-yGex Cy epitaxial layers on Si(100) was performed using silicided platinum Schottky contacts. XRD studies show Pt silcidation of SiGeC proceeds from non-reacted Pt to Pt2(SiGeC) and

This paper describes continuing work with three-dimensional (3-D) rotating line-scan vision systems in robotics and measurement. Mathematical algorithms have been developed for use with the line-scan arrangement allowing the extraction of three-dimen

Polycrystalline Al2O3 was chemically vapor-deposited onto sintered Al2O3 substrates by reaction of AlCl3 with (1) H2O, (2) CO:H2, and (3) O2 at 1000° and 1500°C and 0.5 and 5.0 torr. Although the thermodynamics of all these reactions predict the fo
