TL;DR: In this paper, a solution-processed infrared photodetector based on lead selenide (PbSe) CQDs blended with low hole mobility polymer poly(N-vinylcarbazole) (PVK) is presented.
Journal ArticleDOI
High performance solution-processed infrared photodiode based on ternary PbSxSe1−x colloidal quantum dots
Muhammad Sulaman,Shengyi Yang,Shengyi Yang,Taojian Song,Haowei Wang,Yishan Wang,Bo He,Miao Dong,Yi Tang,Yong Song,Bingsuo Zou +10 more
TL;DR: In this paper, a solution-processed near-infrared photodiode ITO/ZnO/PbSxSe1−x/Au, in which ternary PbS xSe 1−x QDs act as the active layer and the ZnO interlayer acts as electron-transporting layer, was demonstrated.
Journal ArticleDOI
Ultra-sensitive solution-processed broadband photodetectors based on vertical field-effect transistor
Muhammad Sulaman,Yong Song,Shengyi Yang,Shengyi Yang,Maoyuan Li,Muhammad Imran Saleem,Perumal Veeramalai Chandraseakar,Yurong Jiang,Yi Tang,Bingsuo Zou +9 more
TL;DR: Novel vertical FET (VFET) based photodetectors are presented, in which the active layer is sandwiched between porous source electrode and planar drain electrode, resulting to ultrashort channel length, promising to fabricate broadband photodETectors with high performance and good stability by this easy approach.
