with a band gap between the lower-energy valence band and the higher-energy conduction band. The energy bands of two-dimensional graphene (right) are smooth-sided cones, which meet at the Dirac point.

comprising two vertically stacked graphene layers, can exploit externally applied electric fields to modulate its electronic band gap—a property essential for electron transport. This ...

Techniques for Band Gap Engineering vary, including doping, the introduction of impurities into a semiconductor to alter its electrical properties; strain engineering, where stress is applied to ...
