Variationally optimized orbital approach to trions in two-dimensional materials
Yao-Wen Chang, Yia-Chung Chang
In this work, trions in two-dimensional (2D) space are studied by variational method with trial wavefunctions being constructed by linear combinations of 2D slater-type orbitals (S…
Bloch-Grüneisen temperature and universal scaling of normalized resistivity in doped graphene revisited
Khoe Van Nguyen, Yia-Chung Chang
In this work, we resolved some controversial issues on the Bloch-Grüneisen (BG) temperature in doped graphene via analytical and numerical calculations based on full inelastic elec…
Gate-tunable exciton-polaron Rydberg series with strong roton effect
Erfu Liu, Jeremiah van Baren, Zhengguang Lu +5
The electronic exciton polaron is a hypothetical many-body quasiparticle formed by an exciton dressed with a polarized electron-hole cloud in the Fermi sea (FS). It is predicted to…
Multipath optical recombination of intervalley dark excitons and trions in monolayer WSe
Erfu Liu, Jeremiah van Baren, Ching-Tarng Liang +5
Excitons and trions (or exciton-polarons) in transition metal dichalcogenides (TMDs) are known to decay predominantly through intravalley transitions. Electron-hole recombination a…
Landau-quantized excitonic absorption and luminescence in a monolayer valley semiconductor
Erfu Liu, Jeremiah van Baren, Takashi Taniguchi +3
We investigate Landau-quantized excitonic absorption and luminescence of monolayer WSe under magnetic field. We observe gate-dependent quantum oscillations in the bright excito…
