GdTe crystals produced by induction melting method, (using Gd and Te in 1:1 atomic ratio see ESI) crystallizes in the well-known NaCl-type fcc structure (SG: Fm-3m) (Figure ) with lattice parameters of a = b = c = 6.25 Å and α = β = γ = 90º. This matches with the optimized lattice parameter of GdTe obtained from the DFT calculations and previously reported values (Figure ). Synthesized sample shows four major peaks corresponding to E 1 g, Ag, B 2 g, and E 2 g modes in the Raman spectrum (Figure ) which confirms its purity . Also, Energy dispersive X-Ray analysis (EDAX) shows the presence of Gd and Te after melting (Figure ).
