摘要：

Nanostructured Nb-doped SrTiO3(001) surfaces were investigated with STM, and the surface patterns for observed nanostructures were assigned. Sequential C-60 deposition onto these nanostructured templates reveals distinct growth modes, including discrete small C-60 islands on the c(4 x 2) reconstruction surface, parallel one-dimensional C-60 chains on (6 x 2) dilines, C-60 double chains on (8 x 2) trilines, epitaxial C-60 close packed adlayers over (11 x 2) tetralines, and two-dimensional ordered C-60 dieter arrays on (7 x 6) waffles. These structural diversities mainly stern from the relatively strong adsorbate-substrate interactions as well as the surface topography demands. The nanostructured oxide surfaces as templates thus have great potential to molecular nanoarchitecture.
