ABSTRACTMercury cadmium telluride epitaxial layers have been grown using methylallyltelluride (MATe), dimethylcadmium (DMCd), and elemental Hg. Using these precursors high quality films have been achieved over the temperature range of 200-300°C. Comparisons are made between UV photon-assisted and thermally deposited films. Composition, growth rate, and electrical properties are compared for the two processes under various parameter conditions. Properties of films deposited on various substrates including CdTe, GaAs, and GaAs/Si are also described.

ABSTRACTA single-and multilayer growth model is presented. Surface order-disorder transitions are studied with the entropy calculated in the Bragg-William approximation and in the quasi-chemical approximation. A plausible explanation for high-quality growth obtained with energy-assistance is given. The model has been extended to study low-temperature epitaxial growth of HgTe and CdTe on different surfaces. The relevant surface energies are evaluated in a Green's function approach.

Abstract AISI Type P20 is a chromium-molybdenum tool steel of medium carbon content. It usually is supplied in the prehardened condition (about 300 Brinell) so that the cavity can be machined and the mold or die placed directly in service; however, for some uses further treatments are employed. It is produced to high-quality tool-steel standards to permit a high luster to be achieved on the surface of the polished die cavity. P20 is used for molds for plastics and for die-casting dies for zinc and other low-temperature casting alloys. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on forming, heat treating, and machining. Filing Code: TS-393. Producer or source: Tool steel mills.

Представлены результаты изучения морфологии поверхности и структуры слоев AlN, сформированных аммиачной МЛЭ на темплейтах 3C-SiC/Si(111) on-axis- и 4° off-axis-разориентации. Опробован технологический режим низкотемпературной эпитаксии зародышевого слоя AlN на поверхности 3C-SiC(111). Среднеквадратичная шероховатость поверхности (5 х 5 мкм) слоев AlN толщиной 150 ± 50 нм составила 2,5-3,5 нм на темплейтах 3C-SiC/Si(111) on-axis и 3,3-3,5 нм на 4° off-axis. Показано уменьшение шероховатости смачивающего слоя AlN при изменении скорости роста. Получены монокристаллические слои AlN(0002) со значениями FWHM (ω-геометрия) 1,4-1,6°. The paper presents the surface morphology and crystal structure of AlN layers formed by ammonia MBE on 3C-SiC/Si(111) on-axis and 4° off-axis disorientation. It offers the technological approach of low-temperature epitaxy of the AlN nucleation layer on the 3C-SiC (111) surface. Root mean square roughness (5 х 5 |xm) of AlN layers with thickness of 150 ± 50 nm was 2,5-3,5 nm onto on-axis templates and 3.3-3.5 nm onto 4° off-axis. It appears that the RMS roughness of the AlN surface is changing with the growth rate variation. Single-crystal AlN(0002) layers with FWHM values (ω-geometry) of 1.4-1.6° have been obtained.
