In this paper Investigations of HgCdTe layers are presented. The layers have been grown on silicon substrate by evaportation technique using a modulated infrared, large power laser beam. The investigated parametaers included resistivity, the Hall coefficient and mobility of n-type layers obtained by means of evaportation of a solid source or power tablet. The results of characterization using Auger spectroscopy are also shown together with AFM results.
In the work results of topographic measurements with the STM (scanning tunneling microscope) for the determination of the surface roughness and grain dimensions of PbTe/BaF₂ layers grown by the source evaporation technique have been presented. The measuremants have been carried out for various substrate temperatures (100 ÷ 400°C) and various power densities of the laser beam. A modulated infrared laser with hv
