Single crystal growth and characterization of LiInSe2

Abstract LiInSe 2 single crystals were grown by directional solidification. The typical as-grown crystal has dimensions of about 20 mm length and 10 mm diameter and shows a deep red color. The lattice constants were determined to be a = 7.218 A, b = 8.441 A, and c = 6.772 A by powder X-ray diffraction. The easiest cleavage plane was estimated to be the b -face. The melting point was determined by differential thermal analysis to be 904°C. The energy band gap of LiInSe 2 at room temperature was estimated by optical transmission measurements to be 1.88 eV. Typical room temperature electrical resistivity was 2.67 × 10 11 Ω cm with n-type conductivity.
