Rashba Effect and Raman Spectra of Tl₂O/PtS₂ Heterostructure.

ABSTRACT: The possibility to achieve charge-to-spin conversion via Rashba spin-orbit effects provides stimulating opportunities toward the development of nanoscale spintronics. Here, we use first-principles calculations to study the electronic and spintronic properties of Tl₂O/PtS₂ heterostructure, for which we have confirmed the dynamical stability by its positive phonon frequencies. An unexpectedly high binding energy of -0.38 eV per unit cell depicts strong interlayer interactions between Tl₂O and PtS₂. Interestingly, we discover Rashba spin-splittings (with a large α _R value) in the valence band of Tl₂O stemming from interfacial spin-orbit effects caused by PtS₂. The role of van der Waals binding on the orbital r
