Abstract

Single crystals of V₂O₅(001) and V₆O¹³(001) were imaged in ambient conditions by scanning tunneling microscopy (STM) and atomic force microscopy (AFM). Atomic-scale resolution images are compared with partial and total electron-density plots of the surface calculated using the extended Hückel tight-binding electronic band-structure method. The V₂O₅(001) surface is terminated by vanadyl O atoms that dominate the contrast in both AFM and STM images. The V₆O₁₃(001) surface, on the other hand, is terminated by a V-O plane and the contrast in both AFM and STM images is dominated by the V atoms.
