Book excerpt: Chromium doped SI GaAs samples annealed at temperatures from 650 C to 950 C were examined for n-type thermal conversion. From Van der Pauw Hall measurements, it was determined that the samples annealed at 850 C, 900 C and 950 C thermally converted. These converted samples were then subjected to resistivity profile measurements to determine the extent of the thermally converted layer. Depth resolved photoluminescence was also used to observe changes in the spectra as surface layers from the converted samples were removed. Although changes in the spectra were observed, none could be related to thermal conversion. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: A photoluminescence study was made of undoped and chromium-doped gallium arsenide annealed in three different atmospheres: argon, hydrogen, and nitrogen. The purpose of this study was to determine the causes of thermal conversion and to examine the effects of different annealing atmospheres on this problem. It was found that conversion can be due to any of the a number of causes, rather than to one common cause. Conversion in the samples studied was associated with carbon impurities in undoped samples and with silicon in doped samples. Although manganese was found to be present in many samples, no clear association of manganese with type conversion was found. It was found that annealing under nitrogen gas was the most effective way of maintaining a semi-insulating surface layer. (Author).
