High quality and high purity MoSe2 Monolayer Film

For applications in tunnel FETs and optoelectronic devices


Monolayer MoSe2 film has a direct bandgap of about 1.5 eV, making it one of the most desirable 2D-layered structures in photovoltaic single-junction solar cells and photoelectrochemical cells. Monolayer MoSe2 film consists of two layers of Se atoms, with one layer of Mo atoms sandwiched in the middle (Se-Mo-Se).

Applications in tunnel FETs and optoelectronic devices

Applications

Having a direct optical band gap of 1.48 eV with a photoluminescence peak at 840 nm, molybdenum diselenide monolayer film is ideal for applications in optoelectronics.

Also, with with its narrower bandgap, higher optical absorbance and larger spin-splitting energy than MoS2, MoSe2 ultrathin films are potentially better than MoS2 for the applications in tunnel FETs and optoelectronic devices.

Synthesis

High-quality molybdenum diselenide monolayer film was grown directly on the substrates (SiO2/Si) by the chemical vapour deposition (CVD) method.

Usage

MoSe2 monolayer film can be used for research purposes such as microscopic analysis, photoluminescence and Raman spectroscopy studies. Monolayer MoSe2 film can also be transferred to other substrates.
