Transport-defined photodetection through electrically selectable nonequilibrium carrier transport
Jiaxuan Cai, Yan Xie, Ning Yang +9
Broadband optical fields can change in both intensity and spectral distribution, but a fixed-response detector maps this evolving information onto a single electrical signal. Here…
Local large temperature difference and ultra-wideband photothermoelectric response of the silver nanostructure film/carbon nanotube film heterostructure
Bocheng Lv, Weidong Wu, Yan Xie +7
Photothermoelectric materials have important applications in many fields. Here, we joined a silver nanostructure film (AgNSF) and a carbon nanotube film (CNTF) by van der Waals for…
Ultrabroadband THz/IR upconversion and photovoltaic response in semi-conductor ratchet based upconverter
Peng Bai, Ning Yang1, Weidong Chu +12
An ultrabroadband upconversion device is demonstrated by direct tandem integration of a p-type GaAs/AlxGa1-xAs ratchet photodetector (RP) with a GaAs double heterojunction LED (DH-…
Realization of ultrabroadband THz/IR photoresponse in a bias-tunable ratchet photodetector
Peng Bai, Xiaohong Li, Ning Yang +14
High performance Terahertz (THz) photodetector has drawn wide attention and got great improvement due to its significant application in biomedical, astrophysics, nondestructive ins…
Tailoring photon emission patterns in nanostructures
Shi-Fang Guo, Suqing Duan, Yan Xie +2
We investigate the photon emission in coupled quantum dots based on symmetry considerations. With the help of a new theorem we proved, we reveal the origin of the various emission…
Photon-assistant Fano resonance in coupled multiple quantum dots
Wanyuan Xie, Hui Pan, Weidong Chu +2
Based on calculations of the electronic structure of coupled multiple quantum dots, we study systemically the transport properties of the system driven by an ac electric field. We…
