Abstract

InxSe1-x (x=0.2 and x=0.6) crystals have been grown by Bridgman/Stockbarger method. The compositional, morphological and structural properties of InxSe1-x semiconductor crystals have been investigated using energy dispersive X-ray (EDX), scanning electron microscopy (SEM) and X-ray diffractometer (XRD) techniques. The freshly cleaved crystals acquired from ingot have mirror-like surface. The powder XRD results revealed that the grown sample was crystalline with a hexagonal structure. SEM image showed that InxSe1-x crystals have smooth, homogenous and layered surface. The crystalline developments in the InxSe1-x crystals have been investigated by X-ray peak broadening. The Williamson Hall (W-H) analysis and size strain plot methods are used to study the individual contributions of crystallite sizes and lattice strain on the peak broadening of the InxSe1-x crystals. The physical parameters such as strain, stress, and energy density values were evaluated more specifically for all the reflection peaks of XRD corresponding to the hexagonal phase of InxSe1-x crystals from the modified form of the W-H plot using uniform deformation model (UDM), uniform stress deformation model (USDM), uniform deformation energy density model (UDEDM) and by the size strain plot method (SSP). The results obtained showed that the mean crystallite size of the InxSe1-x crystals determined from the W-H analysis and the SSP methods are inter-correlated.
