Abstract

<abstract abstract-type="graphical" xml:lang="en" id="crat201300126-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p>Complex studies of novel Tl_1–xIn_1–xSn_xS₂ single crystalline alloys (x = 0.1; 0.2; 0.3; 0.4; 0.5) were performed. Here we present the study of the effect of the partial cation substitution of Sn ions by In ions on their optical absorption and photoconductivity characteristics. The dependences of optical and electric properties of the crystals of the crystalline solid solutions on temperature and composition are discussed within a framework of intrinsic defect states forming then fundamental absorption. The calculations of the charged defects responsible for the experimentally determined values of Δ₀ were done. Some increase of the concentration for charged defects with the sample temperature is probably related to the thermal ionization of some of the defects that were neutral at lower temperature. The results obtained will be analyzed within the framework of the intrinsic defect's model. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg26mdgc3w" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
