MoSe2 Few-Layer Film, with high electrical conductivity

Great potential for energy processing and storage devices


Molybdenum diselenide (MoSe2) few-layer films have electrical and optical properties that are dependent on the number of layers a film has. Few-layer MoSe2 nanosheets have a high surface area and unique electronic (quasiparticle bandgap) properties due to interlayer coupling and screening effects. The band gap varies from 1.50 eV (in a monolayer) to 1.1 eV (in a bulk counterpart).

Applications

Molybdenum diselenide few-layer films show great potential in energy processing and storage devices (such as lithium and sodium ion batteries) due to their large interlayer spacing (0.64 nm) and higher electrical conductivity.

It has also been widely used in lasers, capacitors, photodetectors, and photoelectrochemical cells as catalysts for hydrogen evolution reactions (HERs).

Synthesis

High-quality molybdenum diselenide few-layer films are directly grown on substrates (SiO2/Si) via the chemical vapour deposition (CVD) method.

Usage

MoSe2 few-layer films can be used for research purposes such as microscopic analysis, photoluminescence and Raman spectroscopy studies. These films can also be transferred to other substrates.
