New materials — primary converters of semiconductor measuring cells based on InAs-CdTe system
Using the method developed with reference to the InAs-CdTe system taking into account its condition diagram and the primary bulk physical, physical and chemical properties of the initial binary compounds (InAs, CdTe), the new materials have been obtained — solid solutions (InAs)x (CdTe)x-1. Ba...

| description | Using the method developed with reference to the InAs-CdTe
system taking into account its condition diagram and the primary
bulk physical, physical and chemical properties of the initial
binary compounds (InAs, CdTe), the new materials have been
obtained — solid solutions (InAs)x
(CdTe)x-1.
Based on the results of X-ray studies in combination with the
results of micro-, electron-microscopic studies, the obtained solid
solutions are certified as substitution solid solution with the cubic
structure of sphalerite.
The acid-base properties of the surfaces of the InAs-CdTe system
components have been studied: the pH values of the isoelectric
state — pHiso — have been found, indicating that the surfaces
belong to a weak-acid region (pHiso<7).
The interconnected patterns in changes with the composition
of the studied bulk and surface properties, respectively,
the relationship between them have been established. The
experimentally confirmed forecasts have been made concerning
the possibilities of a preliminary assessment of the nature of the
ρr
concentration dependence and the increased sensitivity of the components surfaces of the studied system to the main gases. The
practical recommendations are given on the use of the obtained
new materials as primary converters of measuring cells for trace
impurities of main gases, in particular ammonia. |
