Аннотация

In this paper, a series of AgxCu1–xGaSe2 (0 ≤ x ≤ 1) solid solution powders were prepared by solid-phase synthesis. The single-phase tetragonal structure of the samples (space group I-42d) was determined by a combination of X-ray phase analysis and Raman spectroscopy. It is shown that their lattice parameters do not conform to the Vegard's law up to x ≈ 0.4. It is found that the width of the forbidden band of the samples also changes nonlinearly: first decreases and then increases. The study of the spectra of low-temperature luminescence and microwave photoconductivity decay has shown that for a series of samples with x from 0 to ≈0.4, and then at the section with x > 0.4, an increase in the lifetime of photogenerated current carriers in AgxCu1–xGaSe2 powders is characteristic. The observed phenomenon seems to be due to the replacement of deep traps for charge carriers, such as selenium vacancies, by smaller cationic vacancies.
