Ultrahigh Photoresponsivity of Gold Nanodisk Array/CVD MoS-based Hybrid Phototransistor
Shyam Narayan Singh Yadav, Po-Liang Chen, Yu-Chi Yao +6
Owing to its atomically thin thickness, layer-dependent tunable band gap, flexibility, and CMOS compatibility, MoS is a promising candidate for photodetection. However, mono-la…

Evidence for Extraction of Photoexcited Hot Carriers from Graphene
Chang-Hua Liu, Nanditha M. Dissanayake, Seunghyun Lee +2
We report evidence of nonequilibrium hot carriers extraction from graphene by gate-dependent photocurrent study. Scanning photocurrent excited by femtosecond pulse laser shows unus…
