ACM12138099-34

Product Name

Structure

CAS

12138-09-9

Density

1 g/cm³

Appearance

Black powder or dispersion

Application

Tungsten disulfide monolayer films show a much higher photoluminescence efficiency and narrower emission line-width than MoS2. Monolayer WS2 films have been widely used in electronic and optoelectronic devices, such as in photovoltaic, FETs, photodetectors, and valleytronic applications.
