Abstract

After Al-treating a gallium crucible, a noticeable improvement to device performance and epilayer surfaces could be seen. This improvement was compared to a device that had the highest reported mid-infrared radiance at time of publication. Using papers and previous growths, the improvement could be narrowed down to the Al-treatment of the gallium crucible. Surface preparation, growth conditions, and device structures tested were as close to identical for before and after Al-treatment.
