Tunable Giant Rashba-type Spin Splitting in PtSe${}_2$/MoSe${}_2$ Heterostructure

Longjun Xiang, Youqi Ke, Qingyun Zhang

We report a giant Rashba-type spin splitting in two-dimensional heterostructure PtSe${}_2$/MoSe${}_2$ with first-principles calculations. We obtain a large value of spin splitting ener…
