Abstract:
1. A thin film transistor device comprising; a plurality of electrically conducting gate electrodes disposed on a substrate; a gate insulator layer disposed on said electrically conducting gate electrodes; an organic semiconductor layer disposed on said insulator layer substantially overlapping said gate electrodes; and a plurality of sets of electrically conductive source and drain electrodes disposed on said organic semiconductor layer such that each of said sets is in alignment with each of said gate electrodes; wherein said organic semiconductor layer is a polycyclic aromatic compound selected from the group consisting of: oligothiophene, perylene, benzo[ghi]perylene, coronene and polyacene, wherein said polycyclic aromatic compound is formed from thermal conversion of a Diels-Alder adduct precursor thereof; wherein said organic semiconductor layer has only a single crystal phase; and wherein a monolayer comprising a material selected from the group consisting of: hexamethyldisilazine (HMDS), aminopropyl triethoxysilane and alkyl trichlorosilane is applied onto said gate insulator layer before deposition of said precursor.
