Abstract

ABSTRACT In this paper, the electronic structures of NbO 2 and Nb 2 O 5 are theoretically and experimentally analyzed. The oxides in the samples are mainly consisted of NbO 2 and NbO, whereas the outmost layer of the samples is NbO 2 . After exposure to air, the outermost layer on all niobium sample...
