Abstract :
The results of the consistent use of in-situ and ex-situ ellipsometry as a control of MCT/CdTe/GaAs heterostructures growth by molecular beam epitaxy (MBE) are presented. It is shown that ellipsometry is able to control the quality of a GaAs substrate preparation prior to epitaxy, to measure the buffer layers and MCT films growth rate, to monitor in-situ composition and surface morphology during deposition process. Temperature measurements of CdTe dielectric functions were made which show the possibility of in-situ determination of surface temperature.
