UV Sensitivity of MOS Structures with Silicon Nanoclusters [PDF]

Sensors, 2019
Selective UV sensitivity was observed in Metal-Oxide-Semiconductor structures with Si nanoclusters. Si nanocrystals and amorphous Si nanoparticles (a-Si NPs) were obtained by furnace annealing of SiOx films with x = 1.15 for 60 min in N2 at 1000 and 700 &

Maximum Metallic Conductivity in Si-MOS Structures [PDF]

Physical Review B, 1998
We found that the conductivity of the two-dimensional electron system in Si-MOS structures is limited to a maximum value, G_{max}, as either density increases or temperature decreases.

Hybrid G/BN@2H-MoS₂ Nanomaterial Composites: Structural, Electronic and Molecular Adsorption Properties

Nanomaterials, 2022
Hybrid structures often possess superior properties to those of their component materials. This arises from changes in the structural or physical properties of the new materials.

Three-Dimensional MoS₂ Nanosheet Structures: CVD Synthesis, Characterization, and Electrical Properties

Crystals, 2023
The proposed study demonstrates a single-step CVD method for synthesizing three-dimensional vertical MoS2 nanosheets. The postulated synthesizing approach employs a temperature ramp with a continuous N2 gas flow during the deposition process.

Research progress of H2S sensors based on metal oxide semiconductor nanomaterials with one-dimensional structures

工程科学学报, 2023
The phenomenon that CuO resistors encounter gas changes opens the prelude to metal oxide semiconductors (MOSs) as gas sensing. From 1953 to 1968, the research and production of MOS gas sensors were unified, but the gas-sensitive materials used at that ...

Black Phosphorus-Molybdenum Disulfide Hetero-Junctions Formed with Ink-Jet Printing for Potential Solar Cell Applications with Indium-Tin-Oxide

Crystals, 2021
In this work, we implemented liquid exfoliation to inkjet-print two-dimensional (2D) black phosphorous (BP) and molybdenum disulfide (MoS2) p–n heterojunctions on a standard indium tin oxide (ITO) glass substrate in a vertical architecture.

Band gap engineering of MoS$_2$ upon compression [PDF]

, 2016
Molybdenum disulfide (MoS$_2$) is a promising candidate for 2D nanoelectronic devices, that shows a direct band-gap for monolayer structure. In this work we study the electronic structure of MoS$_2$ upon both compressive and tensile strains with first ...
