To improve the transfer characteristics of the single molecular transistor (SMT) based on heteroepitaxial spherical (HS-) Au/Pt nanogap electrodes, the arrangement of HS-Au particles grown on the top of the source and drain electrodes within the nanogap must be considered. In this study, comparing with the SEM top-view images of HS-Au/Pt nanogap electrodes with thin and thick Pt deposited thickness, the optimization of the arrangement of HS-Au/Pt nanogap electrodes was discussed for the improvement of the transfer characteristics.
