    • High-pressure structural phase transitions in semiconducting niobium dioxide 

      Haines, Julian; Leger, Jean Michel; Pereira, Altair Soria; Häusermann, D.; Hanfland, M. (1999) [Artigo de periódico]
      Niobium dioxide was studied up to 47 GPa by angle-dispersive, x-ray powder diffraction. Semiconducting α − NbO 2 (space group I 4 1 / a , Z = 32 ) was found to transform to β − NbO 2 (space group I 4 1 , Z = 16 ) above 5 ...
