Electrons, holes, and spin in the IV-VI monolayer 'four-six-enes'
Ian Appelbaum, Pengke Li
Bandedge states in the indirect-gap group-IV metal monochalcogenide monolayers ('four-six-enes' such as SnS, GeTe, etc.) inherit the properties of nearby reciprocal space points of…

Electrons and holes in phosphorene
Pengke Li, Ian Appelbaum
We present a symmetry analysis of electronic bandstructure including spin-orbit interaction close to the insulating gap edge in monolayer black phosphorus ('phosphorene'). Expressi…

Intrinsic Spin Lifetime of Conduction Electrons in Germanium
Pengke Li, Yang Song, Hanan Dery
We investigate the intrinsic spin relaxation of conduction electrons in germanium due to electron-phonon scattering. We derive intravalley and intervalley spin-flip matrix elements…
