Coordenação de Aperfeiçoamento de Pessoal de Nível SuperiorBoron nitride (BN) is a compound formed by covalent bonds between boron and nitrogen atoms. In the crystalline phase it can be found in different structures, such cubic (c-BN), simgle hexagonal (h-BN), wurtzite (w-BN) and rhombohedral (r- BN). Similarly to graphite h-BN can form two dimensional structures, which can be cut to form tubes. Otherwise, c-BN has hardness similar to diamond, which is retained up to 2000 °C while diamond turns into to graphite at about 900 °C. These properties make BN a promissor material for nanoelectronics in a hot environment. Here, we investigate structural and electronic properties of BN nanotubes. Our study is directed not only to BN nanotubes in the...
