We demonstrated fabrication of nanogap electrodes with flat and thin Au films by using laterally enhanced growth of Au electrodeposition and applied the electrodes for electrical measurement of poly(3-methylthiophene) (P3MT) nanowires. The Au electrodeposition was performed on microgap electrodes following an organic modification process on an insulator surface of the microgap electrodes. Then, P3MT nanowires were aligned between the nanogap electrodes for transistor property measurement. The result suggested that the fabricated nanogap electrodes were suitable to apply for electrical properties measurement of such organic nanowires because of small difference in height between top of the electrodes and the insulator surface.
