Enhanced NO₂ Sensing Performance of ZnO-SnO₂ Heterojunction Derived from Metal-Organic Frameworks

Nanomaterials, 2022
Nitrogen dioxide (NO2) is the major reason for acid rain and respiratory illness in humans. Therefore, rapid, portable, and effective detection of NO2 is essential. Herein, a novel and simple method to construct a ZnO-SnO2 heterojunction is fabricated by

MoS2 Heterojunctions by Thickness Modulation [PDF]

Scientific Reports, 2015
AbstractIn this work, we report lateral heterojunction formation in as-exfoliated MoS2 flakes by thickness modulation. Kelvin probe force microscopy is used to map the surface potential at the monolayer-multilayer heterojunction and consequently the conduction band offset is extracted.

Effect of doping on performance of organic solar cells

, 2011
Conventional models of planar and bulk heterojunction organic solar cells have been extended by introducing doping in the active layer. We have studied the performance of organic solar cells as a function of dopant concentration.

2D/2D Heterojunctions for Catalysis [PDF]

Advanced Science, 2019
Abstract2D layered materials with atomic thickness have attracted extensive research interest due to their unique physicochemical and electronic properties, which are usually very different from those of their bulk counterparts. Heterojunctions or heterostructures based on ultrathin 2D materials have attracted increasing attention due to the integrated

Suppressed spin dephasing for 2D and bulk electrons in GaAs wires due to engineered cancellation of spin-orbit interaction terms [PDF]

, 2010
We report a study of suppressed spin dephasing for quasi-one-dimensional electron ensembles in wires etched into a GaAs/AlGaAs heterojunction system. Time-resolved Kerr-rotation measurements show a suppression that is most pronounced for wires along the [

NO2 sensing characteristics by α-Fe2O3 nanorod arrays with atomic layer deposited amorphous Al2O3 overlayer

Nano Express
We have grown α -Fe _2 O _3 nanorods by solution processing followed by the deposition of Al _2 O _3 overlayer using atomic layer deposition. Al _2 O _3 layer was deposited for two different thicknesses 4 nm and 8 nm and a post-deposition annealing at ...
