Electric-field-tunable intervalley excitons and phonon replicas in bilayer WSe
Mashael M. Altaiary, Erfu Liu, Ching-Tarng Liang +7
We report the direct observation of intervalley exciton between the Q conduction valley and valence valley in bilayer WSe by photoluminescence. The Q exciton lies at ~18…
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…
Effective bond-orbital model of III-nitride wurtzite structures based on modified interaction parameters of zinc-blende structures
Fu-Chen Hsiao, Ching-Tarng Liang, Yia-Chung Chang +1
A simple theoretical method for deducing the effective bond-orbital model (EBOM) of III-nitride wurtzite (WZ) semiconductors is presented. In this model, the interaction parameters…
