Light-induced quantum anomalous Hall effect on the 2D surfaces of 3D topological insulators
Haowei Xu, Jian Zhou, Ju Li
Quantum anomalous Hall (QAH) effect generates quantized electric charge Hall conductance without external magnetic field. It requires both nontrivial band topology and time-reversa…
Revealing the Brønsted-Evans-Polanyi Relation in Halide-Activated Fast MoS2 Growth Towards Millimeter-Sized 2D Crystals
Qingqing Ji, Cong Su, Nannan Mao +7
Achieving large-size two-dimensional (2D) crystals is key to fully exploiting their remarkable functionalities and application potentials. Chemical vapor deposition (CVD) growth of…
Colossal switchable photocurrents in topological Janus transition metal dichalcogenides
Haowei Xu, Hua Wang, Jian Zhou +3
Nonlinear optical properties, such as bulk photovoltaic effects, possess great potential in energy harvesting, photodetection, rectification, etc. To enable efficient light-current…
Giant Photonic Response of Mexican-hat Topological Semiconductors for Mid-infrared to THz Applications
Haowei Xu, Jian Zhou, Hua Wang +1
The mid-infrared (MIR), far-infrared (FIR) to terahertz (THz) frequencies are the least developed parts of the electromagnetic spectrum for applications. Traditional semiconductor…
Competing dynamics of single phosphorus dopant in graphene with electron irradiation
Cong Su, Mukesh Tripathi, Qing-Bo Yan +10
Atomic-level structural changes in materials are important but challenging to study. Here, we demonstrate the dynamics and the possibility of manipulating a phosphorus dopant atom…
