Ferroelectric gating of the PL in MoSe2
Xiaoyu Mao, Jun Fu, Ming Gong +1
We demonstrate a 2D ferroelectric heterostructure with monolayer MoSe and CuInPS (CIPS). In the heterostructure, the electric polarization of CIPS results in c electron…
Approaching Three-Dimensional Quantum Hall effect in Bulk HfTe5
Pang Wang, Yafei Ren, Fangdong Tang +5
The discovery of quantum Hall effect in two-dimensional (2D) electronic systems inspired the topological classifications of electronic systems1,2. By stacking 2D quantum Hall effec…
Non-volatile ferroelectric memory effect in ultrathin α-In2Se3
Siyuan Wan, Yue Li, Wei Li +8
Recent experiments on layered α-In2Se3 have confirmed its room-temperature ferroelectricity under ambient condition. This observation renders α-In2Se3 an excellent platform for dev…
A switchable diode based on room-temperature two-dimensional ferroelectric α-In2Se3 thin layers
Siyuan Wan, Yue Li, Wei Li +3
Nanoscaled room-temperature ferroelectricity is ideal for developing advanced non-volatile high-density memories. However, reaching the thin film limit in conventional ferroelectri…
Observation of Exciton-Phonon Sideband in Individual Metallic Single-Walled Carbon Nanotubes
Hualing Zeng, Hongbo Zhao, Fu-Chun Zhang +1
Single-walled carbon nanotubes (SWCNTs) are quasi-one-dimensional systems with poor Coulomb screening and enhanced electron-phonon interaction, and are good candidates for excitons…
