Engineering the strain and interlayer excitons of 2D materials via lithographically engraved hexagonal boron nitride
Yu-Chiang Hsieh, Zhen-You Lin, Shin-Ji Fung +11
Strain engineering has quickly emerged as a viable option to modify the electronic, optical and magnetic properties of 2D materials. However, it remains challenging to arbitrarily…
Large shift current via in-gap and charge-neutral exciton excitations in BN nanotubes and single BN layer
Yi-Shiuan Huang, Yang-Hao Chan, Guang-Yu Guo
We perform {\it ab initio} many-body calculations to investigate the exciton shift current in small diameter zigzag BN nanotubes and also single BN sheet, using the GW plus Bethe-S…
Evidence of high-temperature exciton condensation in a two-dimensional semimetal
Qiang Gao, Yang-hao Chan, Yuzhe Wang +10
Electrons and holes can spontaneously form excitons and condense in a semimetal or semiconductor, as predicted decades ago. This type of Bose condensation can happen at much higher…
Nature of novel moiré exciton states in WSe/WS heterobilayers
Mit H. Naik, Emma C. Regan, Zuocheng Zhang +18
Moiré patterns of transition metal dichalcogenide (TMD) heterobilayers have proven to be an ideal platform to host unusual correlated electronic phases, emerging magnetism, and cor…
Unmasking the Origin of Kinks in the Photoemission Spectra of Cuprate Superconductors
Zhenglu Li, Meng Wu, Yang-Hao Chan +1
The origin of a ubiquitous bosonic coupling feature in the photoemission spectra of high-Tc cuprates, an energy-momentum dispersion 'kink' observed at ~70 meV binding energy, remai…
Predominance of non-adiabatic effects in zero-point renormalization of the electronic band gap
Anna Miglio, Véronique Brousseau-Couture, Emile Godbout +6
Electronic and optical properties of materials are affected by atomic motion through the electron-phonon interaction: not only band gaps change with temperature, but even at absolu…
