Acoustoelectric Probing of Fractal Energy Spectra in Graphene/hBN Moiré Superlattices
Wenqing Song, Yicheng Mou, Qing Lan +6
Moiré superlattices with long-range periodicity exhibit Hofstadter energy spectra under accessible magnetic fields, enabling the exploration of emergent quantum phenomena through…
Coherent detection of the oscillating acoustoelectric effect in graphene
Yicheng Mou, Jiayu Wang, Haonan Chen +9
In recent years, surface acoustic waves (SAWs) have emerged as a novel technique for generating quasiparticle transport and band modulation in condensed matter systems. SAWs intera…
Acousto-drag photovoltaic effect by piezoelectric integration of two-dimensional semiconductors
Jiaming Gu, Yicheng Mou, Jianwen Ma +11
Light-to-electricity conversion is crucial for energy harvesting and photodetection, requesting efficient electron-hole pair separation to prevent recombination. Traditional juncti…
Memristive switching in the surface of a charge-density-wave topological semimetal
Jianwen Ma, Xianghao Meng, Binhua Zhang +20
Owing to the outstanding properties provided by nontrivial band topology, topological phases of matter are considered as a promising platform towards low-dissipation electronics, e…
