Paper Abstract

The successful fabrication of long wavelength Hg1-yCdyTe/Hg1-xCdxTe heterostructures (Y$GTRx) on semi- insulating (111)CdZnTe substrates is presented. The heterostructures consist of a thin 2-5 micrometers layer on n-type 10- 15 micrometers thick HgCdTe epilayer. A novel tipping boat for liquid phase epitaxial growth of mercury cadmium telluride from Te-rich solutions has been proposed. The characterization of double- layer heterostructures was carried out using different methods: microscopic examinations, infrared microscopic transmission, and scanning electron microscopic measurements. Electrical properties were measured in temperature range of 77-300 K using the Van der Pauw arrangement. By optimizing the growth parameters and the construction of graphite boat it was possible to obtain high quality, relatively abrupt Hg1-xCdxTe heterostructures.
