MoWSe2 Powder, high quality 2D TMDC alloy

Monolayers exhibit strong photoluminescence emission


| | | | |


Molybdenum tungsten diselenide (MoWSe2), CAS number 126414-37-7, is a 2D TMDC alloy. Alloying 2D TMDCs has proven to be an effective way of modulating the band gap because of the good thermodynamic stability (at room temperature) of the alloys.

Applications

applications in photodetectors, FETs, LEDs and photovoltaic devices

MoWSe2 monolayers consist of two Se atomic layers and a sandwiched metal (Mo/W) atom layer. The monolayer of MoWSe2 shows alternating atomic arrangement of Mo and Se sites in the hexagonal rings, with the Mo atoms partially and randomly substituted by W atoms compared to MoSe2. Like graphite, its interlayers are bound by weak van der Waals.

Viscoelastic Transfer of 2D Material Using PDMS

Viscoelastic transfer using polydimethylsiloxane (PDMS) stamps is one of the methods used for the deterministic placement of 2D materials and the fabrication of van der Waals heterostructures. It relies on the viscoelasticity of PDMS, which behaves as an elastic solid on short time scales, but as a viscous fluid on long time scales.
