“…The phase diagram of this system, growth of undoped Ag x Ga x Ge 1 -x Se 2 (0.1 ≤ x ≤ 0.4) single crystals, and their electrical and optical properties were reported earlier [1][2][3][4]. Ag x Ga x Ge 1 -x Se 2 crystals were shown to be p -type semiconductors with a band gap of about 0.26 eV near 290 K.…”

“…Завдяки ацентросиметричності кристалічної структури сполуки є перспективними матеріалами нелінійної оптики [2]. Крім того, для цих систем характерне утворення твердих розчинів на основі A I C III X 2 , механізм формування яких полягає у поступовому заміщенні атомів елементів III групи на атоми елементів IV групи у їх кристалографічних позиціях, натомість, кристалографічні позиції атомів I групи стають дефектними [3]. Для цих систем найбільш типовими є сполуки складів A [2] та AgGaGeS 4 (ПГ Fdd2) [4].…”

“…Для цих систем найбільш типовими є сполуки складів A [2] та AgGaGeS 4 (ПГ Fdd2) [4]. У системі AgGaSe 2 -GeSe 2 також утворюється сполука складу AgGaGe 3 Se 8 , яка кристалізується у просторовій групі Fdd2 [5].…”

“…The crystalline lattice of AgGaGe 3 Se 8 can be represented as a cluster formed by Se atoms surrounding a statistical mixture 0.25Ga +0.75Ge, with Ag atoms being located in the voids of the clusters [2]. In general, the AgGaGe 3 Se 8 crystals are transparent in the spectral range from 600 to 16000 nm, although they manifest a number of absorption peaks located at 2844.1, 10020.0, 12853.5 and 13297.9 nm [3,4].…”

“…So, the electric, optical and thermoelectric properties of AgGaGe 3 Se 8 indicate that it may find its practical applications in the nonlinear optics and fabrication of heterojunctions, along with wide-gap II-VI chalcogenides that are typically of n-type [5]. The studies of mixed crystals Ag x Ga x Ge 1-x Se 2 have shown that AgGaGe 3 Se 8 occupies a special position in this family and deserves further attention, especially in relation to its composition stability in the growth process [1].…”
