An in-situ spectroscopic ellipsometer has been equipped on a molecular beam epitaxy system to improve control of HgCdTe growth. Using this device, in-situ analysis of composition, growth rate, and surface cleanliness were monitored. A real time model which determined the compositional profile was used. The ellipsometer was employed to give in-situ real time control of the growth process.
