Electronic structure and optical properties of ternary CdXP2 semiconductors (X=Si, Ge and Sn) under pressure

The reflectivity spectra of ZnXP2 (X=Si, Ge, and Sn) compounds

“…Recently, the development of the Augmented Plane Wave (APW) methods from Slater's APW to LAPW and the new APW+lo was described by Schwarz et al and Sjo¨stedt et al [14][15][16].…”

The role of acoustic phonon anharmonicity in determining thermal conductivity of CdSiP2 and AgGaS2: First principles calculations

“…6 Many theoretical and experimental works have helped to explain the electronic and optical properties of these compounds. 4,[7][8][9][10] Thermal conductivity is a particularly important physical property of ternary chalcopyrite single-crystal materials that influences crystal growth and is crucial for the application of ternary chalcopyrite in lasers and optical devices. For instance, heat flux induced by an incident laser can be effectively conducted away from a device with high thermal conductivity, thereby preventing damage to the material.…”

Growth and characterization of large CdSiP2 single crystals

“…They can, however, be plagued by defect related absorption losses near the band edge when grown from the melt, but these can often be eliminated by post-growth processing. CdSiP 2 is a II-IV-V 2 compound that has been examined by several authors starting in the late 1960s [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. Borshchevskii et al [5] reported halogen assisted vapor transport growth of the compound as early as 1967, and Spring-Thorpe and Pamplin [4] reported growth from molten tin solution in 1968.…”

“…The birefringence of tiny 2 Â 2 Â 0.2 mm 3 CdSiP 2 crystals grown from a molten tin flux was measured by Itoh et al [2] and found to be À 0.045 at 840 nm. More recent studies examined the cathodoluminescence [11] and nuclear magnetic resonance (NMR) spectra [12] of small CdSiP 2 crystalline samples, and recent theoretical studies examined the calculated electronic band structure [13][14][15][16]. Crystals grown through either solution or halogen-assisted vapor transport were never of sufficient size or quality to create non-linear optical devices or to measure the ordinary and extraordinary refractive index of CdSiP 2 as a function of wavelength throughout its transparency range to determine if it could be phase matched.…”
