Ba<sub>2</sub>HgTe<sub>5</sub>: a Hg-based telluride with giant birefringence induced by linear [HgTe<sub>2</sub>] units
Mengran Sun, Jiyong Yao
Abstract
Ba 2 HgTe 5 , the first Hg-based telluride birefringent material, was successfully synthesized. The analysis of the response electron distribution anisotropy illustrates that the large birefringence of Ba 2 HgTe 5 originates from the linear [HgTe 2 ] unit.
