Growth of sexithiophene crystals on Cu(1 1 0) and Cu(1 1 0)-(2×1)O stripe phase-The influence of surface corrugation

On the striped surface clean copper- and oxygen-passivated copper regions are offered on the same surface. The dominant crystalline fraction grows in an orientation also found on the fully reconstructed Cu(1 1 0)-(2×1)O surface where it grows exclusively in this orientation. A model that explains these experimental findings is discussed and it turns out that the sticking anisotropy is the dominating effect.
