Abstract

For the first time the synthesis of the solid solutions AgGaₓIn₁₋ₓSe₂ has been made successfully for various values of x. It has been found by X-ray diffraction that all samples have the chalcopyrite type crystal structure. The unit-cell parameters a and c and their ratio c/a vary linearly with x and that fact can be connected with the dimensions of atoms.
The band width E₉ increases linearly with x from 1.19 to 1.77 eV. The electric conductivity varies for several orders of magnitude with change of x from 0 to 1. Using thermoelectric probe it has been noticed that all compounds have n-type conductivity for x < 1.
