WS2 on GaAs substrate

Our company is currently able to manufacture high quality monolayer WS2  films.
The largest 4 inch discs are currently available, and larger sizes (8, 12 inches) are coming soon.

Production method:

Chemical Vapor Deposition （CVD）

Product introduction:

Molybdenum disulfide films have sevaral kinds:
1) A single-layer discretely distributed triangular single crystal grain whose triangular side length is generally several tens to one hundred micrometers.
2) A single-layer continuous film that continues to grow in Dalian by triangular grains.
3) Multilayer MoS2 continuous film.
4) Substrate: MoS2 has many optional substrates, among which the most commonly used   sapphire substrate are direct deposition products. Other substrates such as PET, PI, ITO, FTO, glass, metal substrates, etc. are transferred to the substrate desired by the customer after growth on sapphire.

The oxide layer has a thickness of 300 nm or other thickness.

This product can choose single side polishing or double side polishing.

Application fields:

Optoelectronic devices, microelectronic devices, biosensing, chemical sensing and other fields.

Packaging and specifications:

10 * 10mm, 15 * 15mm, 20 * 20mm, 2" disc, 4" disc or custom size specified by the customer.
Purification vacuum packaging, 1 piece / box, 5 pieces / box. 10 pieces / box.
