Study of molecular beam epitaxial growth and optical characteristics of HgCdTe

HgCdTe epilayers were grown by molecular beam epitaxy on GaAs(211)B substrates. Process of the HgCdTe epitaxial growth can be monitored by reflection high-energy electron diffraction. Results of the infrared transmission spectrum, Raman scattering spectrum and infrared photoluminescence spectrum in magnetic field have been studied.
