Giant room-temperature nonlinearities from a monolayer Janus topological semiconductor
Jiaojian Shi, Haowei Xu, Christian Heide +16
Nonlinear optical materials possess wide applications, ranging from terahertz and mid-infrared detection to energy harvesting. Recently, the correlations between nonlinear optical…
Non-invasive improvement of machining by reversible electrochemical doping: a proof of principle with computational modeling
Anastassia Sorkin, Yunfa Guo, Manabu Ihara +2
We propose that the machinability of hard ceramics can be improved by reversible electrochemical doping. On the example of TiO2, we show in a combined density functional theory-mol…
Effect of a weak magnetic field on ductile-brittle transition in micro-cutting of single-crystal calcium fluoride
Yunfa Guo, Yan Jin Lee, Yu Zhang +3
Magneto-plasticity occurs when a weak magnetic field alters material plasticity and offers a viable solution to enhance ductile-mode cutting of brittle materials. This study demons…
Spectroscopic Signatures of Interlayer Coupling in Janus MoSSe/MoS2 Heterostructures
Kunyan Zhang, Yunfan Guo, Daniel T. Larson +5
The interlayer coupling in van der Waals heterostructures governs a variety of optical and electronic properties. The intrinsic dipole moment of Janus transition metal dichalcogeni…
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…
Designing Artificial Two-Dimensional Landscapes via Room-Temperature Atomic-Layer Substitution
Yunfan Guo, Yuxuan Lin, Kaichen Xie +21
Manipulating materials with atomic-scale precision is essential for the development of next-generation material design toolbox. Tremendous efforts have been made to advance the com…
Weak antilocalization and electron-electron interaction in coupled multiple-channel transport in a BiSe thin film
Yumei Jing, Shaoyun Huang, Kai Zhang +5
Electron transport properties of a topological insulator BiSe thin film are studied in Hall-bar geometry. The film with a thickness of 10 nm is grown by van der Waals epita…
