LiGaTe2 (LGT) nonlinear crystal: Synthesis and crystal growth processes exploration

Ba2HgTe5: a Hg-based telluride with giant birefringence induced by linear [HgTe2] units

“…Notably, the peaks at 398 °C and 363 °C can be attributed to the melting and recrystallization of the Te impurity, respectively. 49 To further confirm the melting behavior of Ba 2 HgTe 5 , the PXRD of the sample after DSC measurement was added. As is shown in Fig.…”

Negative thermal expansion and electronic structure variation of chalcopyrite type LiGaTe2

“…LiGaTe 2 crystals were obtained in three stages. 37 At the first stage, we obtained the charge by fusing the elementary components Li, Ga, and Te in a glass carbon crucible inside the sealed quartz ampoule. The ampoule was evacuated to the residual pressure of 10 −3 atm.…”

Growth, Structure, and Optical Properties of Nonlinear LiGa0.55In0.45Te2 Single Crystals

“…Crystals of LiGa x In 1– x Te 2 were obtained similarly to LiGaTe 2 (LGT). ,− Weighing and loading of initial elementary substances were carried out in a dry chamber purged with pure argon. The original elementary substances had a purity qualification of O. S. Ch.…”

“…LiInTe 2 compounds have been known since 1985, , but only as powders. LiGaTe 2 crystals were only grown recently. − They were shown to crystallize in the same chalcopyrite-type structure as for the well-known AgGaS 2 and AgGaSe 2 , and active research of tellurides is in progress. Tellurides are characterized by a rather low melting point (about 660 °C), which allows one to reduce the probability of explosion during growth and to improve the quality of crystals.…”
