Large spin splitting in the conduction band of transition metal dichalcogenide monolayers
We study the conduction band spin splitting that arises in transition metal dichalcogenide (TMD) semiconductor monolayers such as MoS2, MoSe2, WS2, and WSe2 due to the combination of spin-orbit coupling and lack of inversion symmetry. Two types of calculation are done. First, density functional theory (DFT) calculations based on plane waves that yield large splittings, between 3 and 30 meV. Sec...
متن کاملAb initio prediction of conduction band spin splitting in zinc blende semiconductors.
We use a recently developed self-consistent GW approximation to present systematic ab initio calculations of the conduction band spin splitting in III-V and II-VI zinc blende semiconductors. The spin-orbit interaction is taken into account as a perturbation to the scalar relativistic Hamiltonian. These are the first calculations of conduction band spin splittings based on a quasiparticle approa...
متن کاملBand-Structure Effects in the Spin Relaxation of Conduction Electrons
Spin relaxation of conduction electrons in metals is significantly influenced by the Fermi surface topology. Electrons near Brillouin zone boundaries, special symmetry points, or accidental degeneracy lines have spin flip rates much higher than an average electron. A realistic calculation and analytical estimates show that these regions dominate the spin relaxation, explaining why polyvalent me...
متن کاملA visible-light-induced overall water-splitting photocatalyst: conduction-band-controlled silver tantalate.
Visible-light-induced water splitting was achieved by increasing the visible-light sensitivity of AgTaO3, by the introduction of Nb, generating AgTa1-xNbxO3. After grafting NiO onto AgTa0.7Nb0.3O3, simultaneous, catalytic liberation of H2 and O2 at a molar ratio of ∼2 : 1 was achieved from pure water under only visible-light irradiation.
متن کاملTHE CONDUCTION BAND SPIN SPLITTING IN TYPE-I STRAINED A N D UNSTRAINED (Galn)As/InP QUANTUM WELLS
-We present the first successful optically detected magnetic resonance experiments (ODMR) on strained and unstrained Ga~In~ _,As/InP type-I quantum wells. The resonances attributed to electrons are in general anisotropic and detailed results are given for the composition range 0.4 < x < 0.6. Extrapolating to the binary end points, i.e. lnAs and GaAs close agreement with existing results is foun...
