Investigation of Deformation and Fracture Mechanisms in Two-dimensional Gallium Telluride Multilayers Using Nanoindentation
Yan Zhou, Shi Zhou, Penghua Ying +12
Two-dimensional (2D) materials possess great potential for flexible devices, ascribing to their outstanding electrical, optical, and mechanical properties. However, their mechanica…
InSe Schottky diodes based on van der Waals contacts
Qinghua Zhao, Wanqi Jie, Tao Wang +2
Two-dimensional semiconductors are excellent candidates for next-generation electronics and optoelec-tronics thanks to their electrical properties and strong light-matter interacti…
The role of traps in the photocurrent generation mechanism in thin In-Se photodetectors
Qinghua Zhao, Wei Wang, Felix Carrascoso-Plana +4
Due to the excellent electrical transport properties and optoelectronic performance, thin indium selenide (InSe) has recently attracted attention in the field of 2D semiconducting…
Second harmonic and sum-frequency generations from a silicon metasurface integrated with a two-dimensional material
Qingchen Yuan, Liang Fang, Hanlin Fang +5
Silicon-based nonlinear metasurfaces were implemented only with third-order nonlinearity due to the crystal centrosymmetry and the efficiencies are considerably low, which hinders…
Towards Air Stability of Ultra-Thin GaSe Devices: Avoiding Environmental and Laser-Induced Degradation by Encapsulation
Qinghua Zhao, Riccardo Frisenda, Patricia Gant +7
Gallium selenide (GaSe) is a novel two-dimensional material, which belongs to the layered III-VIA semiconductors family and attracted interest recently as it displays single-photon…
Multiple optical frequency-conversions in few-layer GaSe assisted by a photonic crystal cavity
Liang Fang, Qingchen Yuan, Hanlin Fang +6
While two-dimensional (2D) materials have intriguing second-order nonlinearities with ultrahigh coefficient and electrical tunability, their atomic layer thicknesses hinder explora…
Microwatts continuous-wave pumped second harmonic generation in few- and mono-layer GaSe
Xuetao Gan, Chenyang Zhao, Siqi Hu +6
We demonstrate the first achievement of continuous-wave (CW) pumped second harmonic generation (SHG) in few- and mono-layer gallium selenide (GaSe) flakes, which are coated on sili…
