Large-scale mapping of moiré superlattices by Raman imaging of interlayer breathing mode and moiré phonons
Kai-Qiang Lin, Johannes Holler, Jonas M. Bauer +6
Moiré superlattices can induce correlated-electronic phases in twisted van-der-Waals materials. Strongly correlated quantum phenomena emerge, such as superconductivity and the Mott…
Topological phonons in oxide perovskites controlled by light
Bo Peng, Yuchen Hu, Shuichi Murakami +2
Perovskite oxides exhibit a rich variety of structural phases hosting different physical phenomena that generate multiple technological applications. We find that topological phono…
Mechanism of carrier localization in doped perovskite nanocrystals for bright emission
Sascha Feldmann, Mahesh Gangishetty, Ivona Bravic +7
Nanocrystals based on metal-halide perovskites offer a promising material platform for highly efficient lighting. Using transient optical spectroscopy, we study excitation recombin…
Phonon-assisted electronic states modulation of few-layer PdSe2 at terahertz frequencies
Ziqi Li, Bo Peng, Miao-Ling Lin +6
Information technology demands high-speed optoelectronic devices, but going beyond the one terahertz (THz) barrier is challenging due to the difficulties associated with generating…
Bright excitons with negative-mass electrons
Kai-Qiang Lin, Chin Shen Ong, Sebastian Bange +15
Bound electron-hole excitonic states are generally not expected to form with charges of negative effective mass. We identify such excitons in a single layer of the semiconductor WS…
