Deformation potentials of the Γ(000) band extrema in CdGa2S4

The band structure of birefractive CdGa2S4 crystals

“…The temperature shift β¼ ΔE/ΔT of bands V 1 À C 1 equals 3.97 Â 10 À 4 eV/K, and that of bands V 2 À С 1 equals 3.21 Â 10 À 4 eV/ K. According to Ref. [17], β equals 2.44 Â 10 À 4 eV/K for couple of bands V 1 Â С 1 . The temperature coefficient of the shift of the bands V 1 Â С 1 и V 2 Â С 1 were determined taking into account that the excitonic maxima in reflection spectra are observed at both low and room temperatures.…”

Interference of birefractive waves in CdGa2S4 crystals

“…[10][11][12][13][14]. Photovoltaic and emission characteristics and the spectrum of local states CdGa 2 S 4 investigated in several studies [15][16][17][18]. High photosensitivity, bright photoluminescence in conjunction with a wide band-gap promote the use of these compounds in semiconductor devices.…”

Optical properties of Cd(Ga 1– x Tm x ) 2 S 4 ( x = 0.01) single crystals

“…1 Introduction CdGa 2 S 4 is a wide-gap semiconductor (Eg = 3.5 eV at 300 K) with high photoconductivity and strong luminescence in the visible region [1][2][3][4]. These desirable properties make this compound a promising optoelectronic material.…”
