In this work, TlIn[Formula: see text]Ga[Formula: see text]Se2 single crystals were grown by zone recrystallization methods and their X-ray phase analysis was performed. The lattice parameters were determined and it was found that crystals based on the original TlIn[Formula: see text]Ga[Formula: see text]Se2 compound crystallized in the same tetragonal symmetry, the space group [Formula: see text]. It was revealed that with partial substitution of indium atoms by gallium atoms in the TlIn[Formula: see text]Ga[Formula: see text]Se2 lattice, the parameters of unit cells change according to the additivity law. First time it was found that with the simultaneous influence of electromagnetic and sound waves, an electromotive force (e.m.f.) occurs or short circuit current. The studies were carried out in the frequency range of electromagnetic radiation of 50–143 kHz. It was revealed that when the investigated crystals were irradiated with magnetic radiation in the absence of sound waves, there was no e.m.f. on the electrodes as well as memory when exposed only to sound. Based on the existing theoretical information, the nature of the revealed single crystal of the acousto-photovoltaic effect was explained.

单晶 TlIn1−xGaxSe2 中的声光电效应研究

在这项工作中，TlIn[公式：见正文]Ga[公式：见正文]Se2通过区域再结晶法生长单晶，并进行了它们的X射线相分析。确定了晶格参数，发现晶体基于原来的TlIn[公式：见正文]Ga[公式：见正文]Se2化合物以相同的四方对称性结晶，空间群[公式：见正文]。结果表明，在 TlIn[公式：见正文]Ga[公式：见正文]Se中，铟原子被镓原子部分取代2晶格中，晶胞的参数按照加法规律变化。首次发现在电磁波和声波的同时影响下，会产生电动势（emf）或短路电流。这些研究是在 50-143 kHz 的电磁辐射频率范围内进行的。结果表明，当研究的晶体在没有声波的情况下用磁辐射照射时，电极上没有电动势，而仅暴露于声音时则没有记忆。根据已有的理论资料，解释了声光光伏效应显露单晶的性质。
