High-efficiency silicon LED with ultra-wideband emission from visible to infrared at room temperature
Xiaobo Li, Jiajing He, Yaping Dan +1
The primary challenge in silicon photonics is achieving efficient luminescence in the communication band, crucial for its large-scale application. Despite significant efforts, sili…
Photon emission gain in Er doped Si light emitting diodes by impact excitation
Huayou Liu, Jiayuan Zhao, Jing Zhang +6
This work demonstrates photon emission gain, i.e., emission of multiple photons per injected electron, through impact excitation in Er-doped silicon light-emitting diodes (LEDs). C…
Rapid quench annealing of Er implanted Si for quantum networking applications
Mark A. Hughes, Huan Liu, Adam Brookfield +3
Erbium implanted silicon (Er:Si) is a promising platform for quantum networking applications, but a major obstacle is the formation of multiple Er centres. We show that the previou…
High Performance MoS2 Phototransistors Photogated by PN Junction
Seyed Saleh Mousavi Khaleghi, Jianyong Wei, Yumeng Liu +4
Photodetectors based on two-dimensional (2D) atomically thin semiconductors suffer from low light absorption, limiting their potential for practical applications. In this work, we…
Analytical photoresponses of Schottky contact MoS2 phototransistors
Jianyong Wei, Yumeng Liu, Yizhuo Wang +10
High-gain photodetectors based on two-dimensional (2D) semiconductors, in particular those in photoconductive mode, have been extensively investigated in the past decade. However,…
Probing the band splitting near the point in the van der Waals magnetic semiconductor CrSBr
Kaiman Lin, Yi Li, Mahdi Ghorbani-Asl +8
This study investigates the electronic band structure of Chromium Sulfur Bromide (CrSBr) through comprehensive photoluminescence (PL) characterization. We clearly identify low-temp…
