Abstract
Crack free LiInSe2 single crystal with bottom dimension of 8mm diameter and 10mm length and top dimension of 12mm diameter and 22mm length was grown using modified vertical Bridgman–Stockbarger method with steady ampoule rotation. The grown LiInSe2 crystal was characterized by X-ray diffraction pattern, Rutherford backscattering spectroscopy (RBS) analysis, Thermogravimetric-Differential thermal (TG-DTA) analysis, optical transmission and microhardness measurements. X-ray diffraction pattern gives the orientation of the crystal as 〈002〉. RBS analysis confirms that the composition of the grown crystal is Li0.8In1.16Se2.04. TG-DTA analysis confirms that the melting point of the grown crystal is 897.5°C. Optical behavior has been assessed by ultraviolet–visible–near infrared spectroscopy and Fourier transform infrared analysis. LiInSe2 optical band gap energy is 2.72eV and the cut off wavelength is 450nm. Mechanical behavior has been studied using Vickers Microhardness measurements.
