Outline of Final Research Achievements

Current standard devices can be realized based on nanomechanical Coulomb blockade shuttle phenomena, which is electron shuttle transportation by mechanical vibration in nanometer scale. Here we fabricated nanogap electrodes on substrates by electron-beam lithography. Combining the nanogap electrodes and metal nanoparticles, single-electron transistors are fabricated and the number of electrons on the nanoparticles are controlled. We also fabricated nanogap electrodes including a beam structure. Under the application of the RF signal, we observe a tunneling current between the nanogap electrodes with the beam structure. The tunneling current shows a peak value at a specific frequency which corresponds to an eigenfrequency of the beam structure. From the peak current value and the eigenfrequency, almost one electron transport in a period of beam vibration. Therefore, electron shuttle phenomena can be demonstrated on solid-state devices.
