Dual quantum confinement and anisotropic spin splitting in the multi-valley semimetal PtSe\(_2\)

By O. Clark and others
We investigate the electronic structure of a two-dimensional electron gas created at the surface of the multi-valley semimetal 1T-PtSe\(_2\). Using angle-resolved photoemission and first-principles-based surface space charge calculations, we show how the induced quantum well subband states form multiple Fermi surfaces which exhibit highly anisotropic Rashba-like spin splittings. We further... Show more
