| Abstract: |
Optical and photoelectric spectral features of AgCd 2 GaS 4 single crystal were explored. Optical band gap energy was estimated from the absorption and was varied within 2.18–2.28 eV (at ambient temperature) for the samples cut from different parts of the single-crystalline specimens. The results of the photoconductivity relaxation study within the temperature range 100–280 K were explored within a framework of the adhesion trapping level model. It was established that the AgCd 2 GaS 4 crystals exhibit long-term relaxation of photoconductivity with adhesion levels at energies about 0.2 eV. [ABSTRACT FROM AUTHOR] |
