In this review, we introduce the current state of the art of the growth technology of pure,
lightly doped, and heavily doped (solid solution) nonlinear gallium selenide (GaSe) crystals …

We have demonstrated a high-average-power, high-repetition-rate optical terahertz (THz)
source based on difference frequency generation (DFG) in the GaSe crystal by using a near …

The objective of this research is to look at how anisotropic mechanical stresses affect the
structural, elastic, and electronic properties of various GaSe polytypes. Density functional …

GaSe 1− x S x (x= 0, 0.01, 0.05, 0.13, 0.22, 0.29, 0.44) crystals were grown by modified
vertical Bridgman method that provided (0001) crystal plane orientation perpendicular to …

Nonlinear optical crystals of gallium selenide are efficient up-and downconverters of infrared

An intensive, broad tunable monochromatic Terahertz (THz) emission is generated from S-
doped (2 wt.%) GaSe (solid solution GaSe 0.91 S 0.09) crystals by collinear difference …

Ambient aging has substantially hindered the development of electronic and optoelectronic
devices made of two-dimensional (2D) semiconducting layered materials because the origin …

The interplanar binding strength of layered GaSe 1-x Te x crystals was directly measured
using a tensile testing machine. The GaSe 1-x Te x crystals were grown by a low …
