Three consecutive quantum anomalous Hall gaps in a metal-organic network
Xiang-Long Yu, Tengfei Cao, Rui Wang +2
In the quantum anomalous Hall (QAH) effect, chiral edge states are present in the absence of magnetic fields due to the intrinsic band topology. In this work, we predict that a syn…
Switchable anomalous Hall effects in polar-stacked 2D antiferromagnet MnBi2Te4
Tengfei Cao, Ding-Fu Shao, Kai Huang +2
Van der Waals (vdW) assembly allows controlling symmetry of two-dimensional (2D) materials that determines their physical properties. Especially interesting is the recently demonst…
Stabilizing polar phases in binary metal oxides by hole doping
Tengfei Cao, Guodong Ren, Ding-Fu Shao +2
The recent observation of ferroelectricity in the metastable phases of binary metal oxides, such as HfO2, ZrO2, Hf0.5Zr0.5O2, and Ga2O3, has garnered a lot of attention. These meta…
Modeling Temperature, Frequency, and Strain Effects on the Linear Electro-Optic Coefficients of Ferroelectric Oxides
Yang Liu, Guodong Ren, Tengfei Cao +2
An electro-optic modulator offers the function of modulating the propagation of light in a material with electric field and enables seamless connection between electronics-based co…
Direct Observation and Control of Surface Termination in Perovskite Oxide Heterostructures
Thomas Orvis, Tengfei Cao, Mythili Surendran +4
The interfacial behavior of quantum materials leads to emergent phenomena such as two dimensional electron gases, quantum phase transitions, and metastable functional phases. Probe…
Ultrahard carbon film from epitaxial two-layer graphene
Yang Gao, Tengfei Cao, Filippo Cellini +5
Atomically thin graphene exhibits fascinating mechanical properties, although its hardness and transverse stiffness are inferior to those of diamond. To date, there hasn't been any…
Optical and electronic properties of two dimensional graphitic silicon carbide
Xiao Lin, Yang Xu, Shisheng Lin +4
Optical and electronic properties of two dimensional few layers graphitic silicon carbide (GSiC), in particular monolayer and bilayer, are investigated by density functional theory…
