Abstract
A method for improving the performance of an organic thin film field effect transistor comprising the steps of: (a) forming a transistor structure having patterned source and drain electrodes; and (b) treating the patterned source and drain electrodes with a thiol compound having the formula, RSH, wherein R is a linear or branched, substituted or unsubstituted, alkyl, alkenyl, cycloalkyl or aromatic containing from about 6 to about 25 carbon atoms under conditions that are effective in forming a self-assembled monolayer of said thiol compound on said electrodes. Organic thin film transistor structures containing the self-assembled monolayer of the present invention are also disclosed.
