Abstract
This paper describes some recent results of the HgCdTe thin film grown directly on different substrates (sapphire, GaAs and Si) by pulsed laser deposition (PLD). The influences of the substrate material on the properties of HgCdTe thin films were investigated by X-ray diffraction (XRD), selected area electron diffraction (SAED), atomic force microscopy (AFM) and energy dispersive X-ray spectroscopy (EDS). It was found that the quality of the HgCdTe film has a strong relation to the structure and properties of the substrate. The experiment results indicate that the HgCdTe epitaxial thin films grown directly on the sapphire substrates have a high quality, and the composition of the films is close to that of the target. While the quality of the HgCdTe films deposited on the Si and GaAs substrates are not very good.
