中文摘要	The growth of pentacene films on different metal (Ga, Pb, Bi, Ag) induced Si(111)-(root 3 x root 3 )R30 degrees surfaces is investigated by scanning tunneling microscopy. On surfaces with high atomic surface roughness, such as Ga/Si-root 3 , beta-Pb/Si-root 3 , and alpha-Bi/Si-root 3 , pentacene forms an initial disordered wetting layer followed by the growth of crystalline thin films. The growth behavior is independent of the metallicity of the substrate surface in this regime. On the other hand, on surfaces with low adatom surface roughness, pentacene molecules form self-organized structures without forming a wetting layer. Moreover, the molecular orientation is critically dependent on the surface metallicity. This work reveals that the growth mode of pentacene on solid surfaces is determined by the combined effects of structural and electronic properties of the substrate.
