Approaching the robust linearity in dual-floating van der Waals photodiode
Jinpeng Xu, Xiaoguang Luo, Xi Lin +9
Two-dimensional (2D) material photodetectors have gained great attention as potential elements for optoelectronic applications. However, the linearity of the photoresponse is often…
High-responsivity MoS hot-electron telecom-band photodetector integrated with microring resonator
Qiao Zhang, Yingke Ji, Siqi Hu +9
We report a high-responsive hot-electron photodetector based on the integration of an Au-MoS junction with a silicon nitride microring resonator (MRR) for detecting telecom-ban…
Tunable linearity of high-performance vertical dual-gate vdW phototransistor
Jinpeng Xu, Xiaoguang Luo, Siqi Hu +8
Layered two-dimensional (2D) semiconductors have been widely exploited in photodetectors due to their excellent electronic and optoelectronic properties. To improve their performan…
Chip-integrated van der Waals PN heterojunction photodetector with low dark current and high responsivity
Ruijuan Tian, Xuetao Gan, Chen Li +7
Two-dimensional materials are attractive for constructing high-performance photonic chip-integrated photodetectors because of their remarkable electronic and optical properties and…
Extraordinary second harmonic generation in ReS2 atomic crystals
Yu Song, Siqi Hu, Miao-Ling Lin +3
We report the observations of unexpected layer-dependent, strong, and anisotropic second harmonic generations (SHGs) in atomically thin ReS2. Appreciable (negligible) SHGs are obta…
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…
