摘要
Sodium chloride is adsorbed at low temperature on Cu(111) and investigated by scanning tunneling microscopy. The ramified shape of the low-temperature grown islands and early second layer nucleation suggest diffusion-limited aggregation of crystallites as corroborated by atomically resolved images of the highly disordered salt clusters. A comparison to single crystalline islands grown at room temperature on Ag(111) reveals differences in bond length and angle and thus crystal order for the low-temperature phase.
