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…
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,…
Broadband photoresponse enhancement by band engineering in Sb-doped MnBi2Te4
Zixuan Xu, Haonan Chen, Jiayu Wang +11
Topological materials have attracted considerable attention for their potential in broadband and fast photoresponse, particularly in the infrared regime. However, the high carrier…
