Graphensic is a new company in Sweden that is a spin-off from the LinkÃ¶ping University. The company aims to produce single layer graphene on hexagonal silicon carbide for the electronic equipment market, and related markets.
Graphensic's technology uses a high temperature process to produce epitaxial graphene on SiC. The high temperature provides better uniformity. Graphensic explains that at lower temperature there are more defects in the SiC substrate. A high temperature is beneficial for the surface kinetics when the graphene layer is formed since carbon atoms are given higher energy to move on the surface. In bilayer or multilayer graphene the silicon is given energy to diffuse away from beneath of the formed graphene layers to create another layer.
