Abstract
We postulate wide-band-gap forms of carbon that locally have a planar bonding configuration as in graphite and, in contrast to diamond, are promising candidates for -type doping by nitrogen. The presence of localized bonds makes them as stable as fullerene and causes large band gaps of eV to appear. The allotropes accept both nitrogen and boron as substitutional dopants, making them potentially extremely useful for high-power, high-temperature, and high-speed device applications.
