Claim:
An organic thin film transistor having a structural arrangement of elements comprising: a substrate, said substrate having an upper and a lower surface; a gate selected from the group consisting of a conductive metal, a doped single crystalline Si, polysilicon, and an organic conductor, having an upper surface, a lower surface and side surfaces, said lower surface of said gate positioned on and in contact with a portion of said upper surface of said substrate; a gate insulator having an upper surface and a lower surface, said lower surface of said gate insulator covering, and in contact with, said upper and side surfaces of said gate, and any remaining exposed area of said substrate not covered by said bottom surface of said gate, said gate insulator being selected from the group consisting of an inorganic oxide dielectric material, and an organic dielectric material, a self-assembled monolayer having an upper surface and a lower surface wherein said lower surface of self-assembled monolayer is formed on and is in contact with said substrate or said upper surface of said gate insulator; an organic thin film semiconductor having an upper surface and a lower surface, and having a thickness of from about 100 to about 1000 Å wherein said lower surface of said organic thin film semiconductor is in contact with said upper surface of said self-assembled monolayer; a source electrode and a drain electrode, each said electrode having an upper surface and a lower surface and being positioned adjacent to each other, said lower surface of said source electrode and said lower surface of said drain electrode being in contact with said upper surface of said organic thin film semiconductor, said self-assembled monolayer comprising a compounds having the formula: RZ wherein Z is a reactive group selected from the group consisting mono-chlorosilane, di-chlorosilane, trichlorosilane, triethoxysilane; mono-chlorogermane, di-chlorogermane, tri-chlorogermane, carboxylic acids, and thiols; said (Z) reactive groups capable forming a covalent bond or strong chemical interaction with said upper surface of said gate insulator or said substrate, said parallel orientation being accomplished using said cyclic ring structures with an odd number of carbon atoms that are attached to said upper surface of said gate insulator or said substrate surface through a single point of attachment, or using said cyclic ring structures with an even number of carbon atoms that are attached to said upper surface of said gate insulator or said substrate through two points of attachment on adjacent ring atoms.
