Abstract

<abstract abstract-type="main"> <title> <x xml:space="preserve">Abstract</x> </title> <sec id="pssb201349030-sec-0001" sec-type="section"> <p>Stable phase CuIn_{1−<italic>x</italic>}Fe_{<italic>x</italic>}S₂ (<italic>x</italic> ≤ 0.10) crystals of chalcopyrite structure were prepared by annealing synthesized CuIn_{1−<italic>x</italic>}Fe_{<italic>x</italic>}S₂ material with the new quasicubic structure of sphalerite type at the high pressure of 5.5 GPa and temperatures ranging from 1170 to 1270 K. CuIn_{1−<italic>x</italic>}Fe_{<italic>x</italic>}S₂ solid solutions were formed by mixing of CuInS₂ and CuFe_1.02S_1.98 that were synthesized in advance. Phase formation in the (1 − <italic>x</italic>)CuInS₂–<italic>x</italic>CuFeS₂ system was investigated and the unit‐cell parameters (the lattice constants and the unit‐cell volume) were computed as a function of composition. In addition, the parameter of the tetragonal distortion (<italic>c</italic>/2<italic>a</italic>) for CuIn_{1−<italic>x</italic>}Fe_{<italic>x</italic>}S₂ solid solutions of chalcopyrite structure was determined.</p> </sec> </abstract>
