Journal ArticleDOI
CdS-Decorated ZnO Nanorod Heterostructures for Improved Hybrid Photovoltaic Devices
TL;DR: The surface modification of ZnO nanorods with CdS leads to an increase in the open circuit voltage and short-circuit current, with enhanced efficiency by 300% over the unmodified ZnNO:P3HT device, because of the cascaded band structure favoring charge transfer to the external circuit.
Journal ArticleDOI
High Efficiency Si/CdS Radial Nanowire Heterojunction Photodetectors Using Etched Si Nanowire Templates
TL;DR: In this article, the photocurrent spectra of the nanowire heterojunctions have been investigated at room temperature to study the spectral responsivity and detectivity of the core-shell nanowires.
Journal ArticleDOI
Highly sensitive large-area multi-layered graphene-based flexible ammonia sensor
TL;DR: In this paper, the authors reported the development of a highly sensitive, flexible and low-cost ammonia sensor based on the chemically derived multilayered graphene deposited on a 3-inch diameter filter paper.
Journal ArticleDOI
Highly Luminescent WS2 Quantum Dots/ZnO Heterojunctions for Light Emitting Devices.
TL;DR: The electroluminescence characteristics are demonstrated for the first time, by forming a heterojunction of stabilizer free WS2 QDs and ZnO thin films, and may pave the way to fabricate prototype futuristic efficient light emitting devices.
Journal ArticleDOI
The effect of substrate temperature on the properties of ITO thin films for OLED applications
TL;DR: In this paper, the structural, electrical and optical properties of indium tin oxide (ITO) thin films have been investigated to obtain optimum values for resistivity, optical transmittance and surface smoothness.
