CAS 12058-18-3 Molybdenum Diselenide(MoSe2) Monolayer Film

Description

Description The direct band gap of monolayer MoSe2 films is about 1.5 eV, making it one of the most desirable 2D layered structures in photovoltaic single-junction solar cells and photoelectrochemical cells. The monolayer MoSe2 film is composed of two layers of Se atoms with a layer of Mo atoms (Se-Mo-Se) sandwiched in between.

Features And Benefits

Features And Benefits Molybdenum diselenide monolayer films have a direct optical bandgap of 1.48 eV and a photoluminescence peak at 840 nm, making them ideal for optoelectronic applications. In addition, MoSe2 ultrathin films have narrower bandgap, higher optical absorption, and larger spin splitting energy than MoS2, which may be superior to MoS2 for applications in tunnel field effect transistors and optoelectronic devices.

Application

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