X-ray dosimetric characteristics of AgGaS2 single crystals grown by chemical vapor transport

Electronic Structure, Optical, and Elastic Properties of AgGaS2 Crystal: Theoretical Study

“…The dosimetric studies demonstrate that the X‐ray sensitivity coefficient of AgGaS 2 single crystal varies from 1.16 × 10 −13 to 1.66 × 10 −12 A min/(V R ) at effective X‐ray hardnesses in the range of V a = 25–50 keV and X‐ray dose rates in the range E = 0.75–78.05 R min −1 . [ 9 ] It was also reported that X‐ray‐induced current through the AgGaS 2 single crystal complies with power law function of X‐ray dose rate, [ 8,9 ] allowing use of the crystal in dosimetry. The X‐ray photoelectron spectroscopy study was performed by M.J. Luciano et.al.…”

“…This crystal has been intensively studied in recent decades, both experimentally and theoretically. [2,[5][6][7][8][9] In particular, AgGaS 2 is a promising material for nonlinear optics and optoelectronics, being one of the most common nonlinear optical crystals commercially available for harmonics generation and parametric generation in the middle and far IR range. The crystal is often used in gas CO 2 lasers due to the high coefficient of effective nonlinearity and high optical bandwidth of the material in the IR range.…”
