Interlayer Ferromagnetism and High-Temperature Quantum Anomalous Hall Effect in \textit{p}-Doped MnBiTe Multilayers
Yulei Han, Shiyang Sun, Shifei Qi +2
The interlayer antiferromagnetic coupling hinders the observation of quantum anomalous Hall effect in magnetic topological insulator MnBiTe. We demonstrate that interlayer…
Nanocavity Induced Light Concentration for Energy Efficient Heat Assisted Magnetic Recording Media
Chenhua Denga, Haomin Song, James Parry +5
Enhancing light absorption in the recording media layer can improve the energy efficiency and prolong the device lifetime in heat assisted magnetic recording (HAMR). In this work,…
Quantum Anomalous Hall Effect and Giant Rashba Spin-Orbit Splitting in Compensated n-p--Codoped Graphene
Xinzhou Deng, Hualing Yang, Shifei Qi +2
Quantum anomalous Hall effect (QAHE) is a fundamental quantum transport phenomenon in condensed matter physics. Until now, the only experimental realization of the QAHE has been ob…
Quantum oscillation in carrier transport in two-dimensional junctions
Junfeng Zhang, Weiyu Xie, Michael L. Agiorgousis +5
Two-dimensional (2D) device structures have recently attracted considerable attention. Here, we show that most 2D device structures, regardless vertical or lateral, act as a latera…
Realization of Quantum Anomalous Hall Effect in Graphene from \textit{n}-\textit{p} Codoping Induced Stable Atomic-Adsorption
Xinzhou Deng, Shifei Qi, Yulei Han +3
Using first-principles calculation methods, we study the possibility of realizing quantum anomalous Hall effect in graphene from stable 3\textit{d}-atomic adsorption via charge-com…
Chalcogenide Perovskites- an Emerging Class of Ionic Semiconductors
Samanthe Pereraa, Haolei Huia, Chuan Zhao +11
We report the synthesis and characterization of a novel class of ionic semiconductor materials- inorganic chalcogenide perovskites. Several different compounds including BaZrS3, Ca…
Realizing Chemical Codoping in Oxide Semiconductors
Fang Wang, Y. Y. Sun, John B. Hatch +6
We demonstrate experimentally a chemical codoping approach that would simultaneously narrow the band gap and control the band edge positions of oxide semiconductors. Using TiO2 as…
