摘要：

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 n-type doping by nitrogen. The presence of localized pi bonds makes them as stable as fullerene C-60 and causes large band gaps of approximate to 3 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.
