Study of temperature dependent phonon properties of SbxGe1-xSe (x = 0.00 and 0.15) crystals

A detailed study of phonon properties of SbxGe1-xSe (x = 0.00 and 0.15) crystals is demonstrated here. DVT technique was employed for crystal growth. Powder XRD confirmed the phase-singularity and revealed the structural minutiae of the grown materials. The surface morphology of the crystals was studied under a high-resolution microscope. Room temperature Raman spectroscopy revealed a blue shift in the out-of-plane mode (B3g) and in-plane modes...
