Large-area MoS2-MoOx heterojunction thin-film photodetectors with wide spectral range and enhanced photoresponse

APL Materials, 2019
We report the enhanced photoresponse in MoS2-MoOx heterojunction thin film structures on SiO2/Si substrates to demonstrate the feasibility of using them as highly responsive photodetectors with a wide spectral range from visible to near-ultraviolet light.

Metal-oxide clusters with semiconductive heterojunction counterparts

Polyoxometalates, 2023
Heterojunctions have received much attention because of their perfect charge-separation effectiveness in improving catalytic/photocatalytic activity, but reproducible formation and nonuniform particle size remain ongoing challenges.

Quantum behavior of graphene transistors near the scaling limit

, 2012
The superior intrinsic properties of graphene have been a key research focus for the past few years. However, external components, such as metallic contacts, serve not only as essential probing elements, but also give rise to an effective electron cavity,

A superlattice interface and S-scheme heterojunction for ultrafast charge separation and transfer in photocatalytic H2 evolution

Nature Communications
The rapid recombination of photoinduced charge carriers in semiconductors fundamentally limits their application in photocatalysis. Herein, we report that a superlattice interface and S-scheme heterojunction based on Mn0.5Cd0.5S nanorods can ...

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.

Impact of Edge States on Device Performance of Phosphorene Heterojunction Tunneling Field Effect Transistors [PDF]

, 2016
Black phosphorus (BP) tunneling transistors (TFETs) using heterojunction (He) are investigated by atomistic quantum transport simulations. It is observed that edge states have a great impact on transport characteristics of BP He-TFETs, which result in ...

Band Alignment in In‐Oxo Metal Porphyrin SURMOF Heterojunctions

Advanced Functional Materials, EarlyView.
Porphyrin core metalation in indium‑oxo SURMOFs enables systematic tuning of band edge positions without altering the crystal structure. First‑principles calculations reveal type‑I and type‑II heterostructures as well as multi‑junction energy cascades, establishing a modular strategy for exciton funneling and charge separation in optoelectronic ...

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 ...
