Recent progress in 2D or 3D N-doped graphene …

Abstract. Nitrogen (N)-doped graphene (N-substituted or nitrogenated graphene) (NG) has become a new class of graphene material due to its modified properties such as the tunable work function, n-type semiconductivity, increasing biocompatibility, and, in particular, the synergistic function with various functional materials.

Silicon Wafer | What Is It and What Is It Used For?

Boron, aluminum, nitrogen, gallium and indium are just some of the silicon dopants that can be introduced during the growth process. Depending on what level the silicon has been doped, the semiconductor can be considered extrinsic or degenerate.

2014-4-25 · Band gaps of boron- and nitrogen-doped graphene transistors showed an on/off ratio of >100 [168, 169]. It also has been reported that by patterned adsorption of atomic H onto the graphene surface, surface absorption can induce a band gap in graphene of at least 450 meV around the Fermi level [ 170 ].
