The mutual influence of surface energy and substrate temperature on the saturation mobility in organic semiconductors

Marco Sarcletti, Thomas Schmaltz, Marcus Halik Abstract We report on a mutual correlation between the substrate temperature during semiconductor deposition and the surface energy of the gate dielectric on the charge carrier mobility in bottom gate top contact organic field effect transistors (OFETs) with N,N′-diphenyl-3,4,9,10-perylene tetracarboxylic diimide (DP-PDI) as organic semiconductor. The gate dielectric consists […]
