Optical spectroscopy of excited exciton states in MoS2 monolayers in van der Waals heterostructures
C. Robert, M. A. Semina, F. Cadiz +12
The optical properties of MoS2 monolayers are dominated by excitons, but for spectrally broad optical transitions in monolayers exfoliated directly onto SiO2 substrates detailed in…
Lattice dynamics and electronic transitions in a structurally-complex layered copper borate Cu(BO)
A. D. Molchanova, M. A. Prosnikov, R. M. Dubrovin +5
Copper borate Cu(BO) is a complex compound with a layered crystallographic structure in which the Jahn-Teller active and magnetic copper Cu ions occupy sixteen n…
Electron spin dynamics of Ce ions in YAG crystals studied by pulse-EPR and pump-probe Faraday rotation
D. V. Azamat, V. V. Belykh, D. R. Yakovlev +6
The spin relaxation dynamics of Ce ions in heavily cerium-doped YAG crystals is studied using pulse-electron paramagnetic resonance and time-resolved pump-probe Faraday rota…
Long-range p-d exchange interaction in a ferromagnet-semiconductor Co/CdMgTe/CdTe quantum well hybrid structure
I. A. Akimov, M. Salewski, I. V. Kalitukha +14
The exchange interaction between magnetic ions and charge carriers in semiconductors is considered as prime tool for spin control. Here, we solve a long-standing problem by uniquel…
Nuclear spin cooling by helicity-alternated optical pumping at weak magnetic fields in -GaAs
P. S. Sokolov, M. Yu. Petrov, K. V. Kavokin +8
The spin dynamics of localized donor-bound electrons interacting with the nuclear spin ensemble in -doped GaAs epilayers is studied using nuclear spin polarization by light with…
Terahertz-driven magnetism dynamics in the orthoferrite DyFeO3
A. H. M. Reid, Th. Rasing, R. V. Pisarev +2
Terahertz driven magnetization dynamics are explored in the orthoferrite DyFeO3. A high-field, single cycle THz pulse is used to excite magnon modes in the crystal together with ot…
