Tetrahedral carbons

Tetrahedral amorphous carbon films have attracted considerable interest because they can be used as an inexpensive and easily produced wide band-gap semiconductor (2.0–2.7 eV) in the fabrication of heterojunction devices, thin film transistors and large area flat-emitter display materials. There have been significant advances, both theoretical and experimental, in this research field, especially in understanding both the effect of ion energy and of doping on the electronic properties of these films.
