Abstract
A model is presented for the reversible phase transition observed for azulene monolayers on Pt(111). Below the transition temperature the overlayer LEED pattern consists of (3×3) aligned with the substrate and (3×3) rotated by 30°. Above the transition temperature the LEED pattern is a (3×3) aligned with the substrate. The model attributes the phase transition to an order–disorder transition of the rotational orientation of azulene molecules with the molecular plane parallel to the surface. (AIP)Keywords
