Large valley splitting in monolayer WS by proximity coupling to an insulating antiferromagnetic substrate
Lei Xu, Ming Yang, Lei Shen +3
Lifting the valley degeneracy is an efficient way to achieve valley polarization for further valleytronics operations. In this work, we demonstrate that a large valley splitting ca…
La interstitial defect-induced insulator-metal transition in oxide heterostructures LaAlO3/SrTiO3
Jun Zhou, Ming Yang, Yuan Ping Feng +1
Perovskite oxide interfaces have attracted tremendous research interest for their fundamental physics and promising all-oxide electronics applications. Here, based on first-princip…
Synthesis, Crystal Structure, Magnetic and Electronic Properties of the Caesium-based Transition Metal Halide Cs3Fe2Br9
Fengxia Wei, Federico Brivio, Yue Wu +3
The diversity of halide materials related to important solar energy systems such as CsPbX3 (X = Cl, Br, I) is explored by introducing the transition metal element Fe. In particular…
Energy transfer channels of the plasmon excitation process in STM tunnel junctions
Yaoqin Lu, Yuntian Chen, Jing Xu +2
We study the decay of gap plasmons localized between a scanning tunneling microscope tip and metal substrate, excited by inelastic tunneling electrons. The overall excited energy f…
Sub-100 nm Skyrmions at Zero Magnetic Field in Ir/Fe/Co/Pt Nanostructures
Pin Ho, Anthony K. C. Tan, S. Goolaup +5
Magnetic skyrmions are chiral spin structures that have recently been observed at room temperature (RT) in multilayer thin films. Their topological stability should enable high sca…
Universality of oscillating boiling in Leidenfrost transition
Mohammad Khavari, Tuan Tran
The Leidenfrost transition leads a boiling system to the boiling crisis, a state in which the liquid loses contact with the heated surface due to excessive vapor generation. Here,…
