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…
Rewritable Complementary Nanoelectronics Enabled by Electron-Beam Programmable Ambipolar Doping
Qing Lan, Wenqing Song, Siyin Zhu +13
The ability to reversibly and site-selectively tune ambipolar doping in a single semiconductor is crucial for reconfigurable electronics beyond silicon, but remains highly challeng…
Observation of ferron transport in ferroelectrics
Kaiwen Shen, Ping Tang, Xianzhe Chen +15
Ferroelectrics feature spontaneous electric dipolar order reconfigurable via electric fields. Recent theoretical studies of the collective excitations of this electric dipolar orde…
Unexpected large electrostatic gating by pyroelectric charge accumulation
Yicheng Mou, Qi Liu, Jiaqi Liu +10
Pyroelectricity refers to the accumulation of charges due to changes in the spontaneous polarization of ferroelectric materials when subjected to temperature variations. Typically,…
