Film Formation on Metallic and Conductive Surfaces

Another way to avoid dewetting is to passivate the metallic surface by a self assembled monolayer (SAM), e.g. an alkane thiol monolayer (C-18). After passivation, the growth structure resembles the growth mode on inert surfaces [33], the same holds for growth of pentacene on conducting polymers such as PEDOT PSS [poly(3,4-ethylenedioxythiophene)/poly(styrenesulfonate)] [39]. It is interesting to note that on bare Si, pentacene initially forms a flat lying monolayer, but on-top of this monolayer, the thin film phase readily forms [16] without need for passivation. 

Brillouin zone. The experiments reveal indieations of strong band dispersion [40]. Reeently, a well defined epitaxial relationship between a pentaeene film and the Bi substrate has been realised. This well defined epitaxial relationship allowed to explore the band dispersion of different erystallographie direetions of the Brillouin zone of pentaeene by APES, also revealing a pronouneed band dispersion [41].
