Graphene band gap heralds new electronics | Research | …

In this method, a silicon carbide (SiC) substrate is heated to temperatures of 1360 C, at which point it begins to decompose and form graphene layers. The researchers found that the first of these layers, normally called the buffer layer, forms a band gap greater than 0.5 eV, because of the highly periodic way it bonds to the SiC substrate.
