Proposed research of a photo-electronic hybrid device utilizing gold nanoparticles GNPs, which are supposed to function not only as the Plasmon antenna but also as the sensing part. The photocurrent in the fabricated device, consisting of a transparent NbdopedTiO2 channel and Au electrodes, was enhanced more than eight times at a specific wavelength with GNP arrays located between the electrodes, indicating that surface Plasmon resonance was electrically detected with the hybrid device. This result will open new doors for ultra-small biosensor chips integrated with multi-functional solid-state devices.
