“…In view of their possible applications in optoelectronic devices in the visible range, a great deal of attention has been devoted to the study of the optical and photoelectrical properties of TlGaS 2 , TlGaSe 2 , and TlInS 2 crystals. [4][5][6][7][8][9][10][11][12] They are of significant interest because of their highly anisotropic properties, semiconductivity, and photoconductivity. Moreover, they exhibit nonlinear effects in I-V characteristics (including a region of negative differential resistance), switching and memory effects.…”

“…Three maxima at ∼98.5 K, ∼119.5 K, and ∼129 K, and a shoulder at ∼140 K emerged. To evaluate the activation energy of traps from the obtained experimental TSC spectra, a curve fitting method based on the slow retrapping model was introduced [20,21,[46][47][48][49][50][51][52][53][54][55]. The following equation is used to describe the complete lineshape of i TSC as a function of temperature [46][47][48][49][50][51][52][53][54][55]:…”

“…where A ∼ 2 mm 2 is the electrode's effective area, V = 7 V is the applied dc bias voltage, and d ∼ 3 mm is the distance between the electrodes. In equation ( 7), i γ TSC is the current contribution from the γth TSC peak, which can be calculated from the equation given as follows [20,21,[46][47][48][49][50][51][52][53][54][55]:…”

“…Исследования изоструктурных кристаллов TlGaSe 2 [3][4][5] и TlInS 2 [6][7][8][9][10][11] показали принципиальную возможность и перспективность фотоэлектрической релаксационной спектроскопии (PICTS [12]) в изучении электрически активных дефектов в сегнетоэлектрикахполупроводниках. Изменения с температурой термоэмиссии неравновесного заполнения центров локализации заряда (ЦЛЗ) в кристалле TlInS 2 , регистрируемые в области температуры сегнетоэлектрического состояния кристалла, хорошо сопоставимы с зависимостью от температуры его поляризационных характеристик [8,9], пироэлектрического тока [10], скорости распространения ультразвука в кристалле [11], а также результатами термостимулированной проводимости [13,14]. Вместе с тем процессы термоэмиссии в сегнетоэлектриках-полупроводниках имеют и свои особенности.…”
