Abstract

Nanostructured Nb-doped SrTiO3(001) surfaces were investigated with STM, and the surface patterns for observed nanostructures were assigned. Sequential C60 deposition onto these nanostructured templates reveals distinct growth modes, including discrete small C60 islands on the c(4 × 2) reconstruction surface, parallel one-dimensional C60 chains on (6 × 2) dilines, C60 double chains on (8 × 2) trilines, epitaxial C60 close packed adlayers over (11 × 2) tetralines, and two-dimensional ordered C60 dimer arrays on (7 × 6) waffles. These structural diversities mainly stem from the relatively strong adsorbate−substrate interactions as well as the surface topography demands. The nanostructured oxide surfaces as templates thus have great potential in molecular nanoarchitecture.
