Investigating Nonlinear Optical and Thermal Properties in Sr2SiSe4 through Noncentrosymmetric Crystal Structure Comparison with Sr2SnSe4

Abstract An isovalent anion substitution approach allowed for the discovery of two noncentrosymmetric ternary selenides, Sr2SiSe4 and Sr2SnSe4. Sr2SiSe4 crystallizes in the α-Eu2GeS4 type, monoclinic space group P21, with lattice parameters a = 6.8866(19) Å, b = 7.0062(19) Å, c =...
