| Summary: | Using the specifically developed method, solid solutions
of the AIIIBV (InSb), AIIBVI (ZnS) type semiconductor
compounds of various composition (InSb)x
(ZnS)1-x have
been obtained. According to the results of the performed
X-ray, micro-, electron-microscopic studies, the obtained
solid solutions are certified as substitutional solid solutions
with a cubic sphalerite structure, data on multicomponent
diamond-like semiconductors has been enlarged.
The chemical composition of the solid solutions surfaces
and binary components of the InSb-ZnS system exposed in
air and in high-vacuum, high-temperature conditions have
been determined.
According to the results of the acid-base properties
studies, the surfaces of the InSb-ZnS system components
exposed in the air are assigned to the weakly acidic
region (pHiso<7). The views on the predominant relative
contribution of Lewis acid sites and the increased activity of surfaces toward the main gases have been stated and
proved. The interrelated consistent patterns of changes in
the composition of bulk and surface properties have been
established. The practicability of their use for a less labour
consuming search for the advanced materials intended for
the sensor technology has been shown.
The obtained solid solutions, specifically those with the
lowest pHiso, are recommended for the manufacture of
the sensors for the main gases, particularly NH3, trace
contamination. |
