Name: 2D MBE WS2
SKU: ACM12138099-48
Rating: 5 (1 reviews)

Description

Description The product is a WS2 monolayer grown by molecular beam epitaxy (MBE). Typical MBE growth on double-sided polished c-cut sapphire yields monolayer-thick WS2 isolated triangles. Currently, MBE WS2 is only available on sapphire substrates, but in the near future our MBE substrates will also include mica, graphite and gold.

Features And Benefits

Features And Benefits MBE growth of WS2 monolayers take place in a MBE chamber at a base pressure of 8E-9 Torr and deposition rate is extremely slow (5-100 atoms per second) to reach structural perfection.

Application

Application WS2 monolayer films can be used for research purposes such as microscopic analysis, photoluminescence and Raman spectroscopy studies.
