Large exciton binding energies in MnPS as a case study of vdW layered magnet
Magdalena Birowska, Paulo E. Faria Junior, Jaroslav Fabian +1
Stable excitons in semiconductor monolayers such as transition-metal dichalcogenides (TMDCs) enable and motivate fundamental research as well as the development of room-temperature…
Strain-tunable orbital, spin-orbit, and optical properties of monolayer transition-metal dichalcogenides
Klaus Zollner, Paulo E. Faria Junior, Jaroslav Fabian
When considering transition-metal dichalcogenides (TMDCs) in van der Waals (vdW) heterostructures for periodic ab-initio calculations, usually, lattice mismatch is present, and the…
Ultralong spin lifetimes in one-dimensional semiconductor nanowires
Florian Dirnberger, Michael Kammermeier, Jan König +9
We experimentally demonstrate ultralong spin lifetimes of electrons in the one-dimensional (1D) quantum limit of semiconductor nanowires. Optically probing single wires of differen…
Spin-orbit coupling effects in zinc-blende InSb and wurtzite InAs nanowires: Realistic calculations with multiband method
Tiago Campos, Paulo E. Faria Junior, Martin Gmitra +2
A systematic numerical investigation of spin-orbit fields in the conduction bands of III-V semiconductor nanowires is performed. Zinc-blende InSb nanowires are considered along [00…
