Photoluminescence switching in a two-dimensional atomic crystal
Zheng Sun, Ke Xu, Chang Liu +5
Two-dimensional materials are an emerging class of new materials with a wide range of electrical and optical properties and potential applications. Single-layer structures of semic…
Tunable ferroelectricity and anisotropic electric transport in monolayer -GeSe
Shan Guan, Chang Liu, Yunhao Lu +2
Low-dimensional ferroelectricity has attracted tremendous attention due to its huge potential in device applications. Here, based on first-principles calculations, we predict the e…
Promising Ferroelectricity in 2D Group IV Tellurides: a First-Principles Study
Wenhui Wan, Chang Liu, Wende Xiao +1
Based on the first-principles calculations, we investigated the ferroelectric properties of two-dimensional (2D) Group-IV tellurides XTe (X=Si, Ge and Sn), with a focus on GeTe. 2D…
Tunable Half-metallic Magnetism in Atom-thin Holey Two-dimensional CN Monolayer
Sai Gong, Wenhui Wan, Shan Guan +5
Exploring two-dimensional (2D) materials with magnetic ordering is a focus of current research. It remains a challenge to achieve tunable magnetism in a material of one-atom-thickn…
Strain effects on electronic and optic properties of monolayer CN holey two-dimensional crystals
Shan Guan, Yingchun Cheng, Chang Liu +4
A new two-dimensional material, the CN holey 2D (CN-2D) crystal, has recently been synthesized. Here we investigate the strain effects on the properties of this new mate…
