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…
