TL;DR: In this article, a comprehensive study employing Raman spectroscopy is reported on N and Li implantation effects in ZnO, showing that the deep acceptor level may be at approximately 300 ǫmeV above the valence band consistent with previous results.
Journal ArticleDOI
Ethylenediamine-Assisted High Yield Exfoliation of MoS2 for Flexible Solid-State Supercapacitor Application
TL;DR: In this paper, a high yield synthesis technique of few-layer MoS2 by ethylenediamine (EDA)-assisted liquid phase exfoliation is reported, which results in larger sized nanosheets up to ∼2.0 μm of lateral dimension having a thickness of ∼2-3 nm with high yield.
Journal ArticleDOI
Improved photovoltaic properties of pentacene/N,N′-Dioctyl-3,4,9,10-perylenedicarboximide-based organic heterojunctions with thermal annealing
TL;DR: In this paper, the effect of thermal annealing on the photovoltaic properties of an organic solar cell based on an efficient donor/acceptor combination of pentacene / N,N′-Dioctyl-3,4,9,10-perylenedicarboximide (PTCDI-C8) discrete heterojunctions was studied.
Journal ArticleDOI
Enhanced Photocurrent Owing to Shuttling of Charge Carriers across 4-Aminothiophenol-Functionalized MoSe2–CsPbBr3 Nanohybrids
Md. Samim Hassan,Pooja Basera,Susnata Bera,Mona Mittal,Samit K. Ray,Samit K. Ray,Saswata Bhattacharya,Sameer Sapra +7 more
TL;DR: The use of a bifunctional ligand to construct a nanohybrid system to tune the optoelectronic properties for potential applications in photovoltaic devices is suggested.
