study charge transport within 2D layers of organic semi-conductors (OSCs) using atomic force microscopy (AFM)-based lithography applied to self-assembled monolayers (SAMs), fabricated from appropriate organothiols. The extent of lateralchargetransport was investigated by insulating pre-defined patches
a top electrode. We were able to determine a relationship between island size and electrical conductivity, and from this dependence, we could obtain information on the lateralchargetransport and charge carrier mobility within the thin OSC layers. Our study demonstrates that AFM nanografting of
the determination of mobilities in macroscopic samples.
