Self-Limiting Dielectrophoretic Process of Gold Nanoparticles for Single-Electron Device Fabrication

Abstract (in Japanese) (See Japanese page) 
(in English) When an electric field is applied to a nanogap placed in a colloidal solution, a dielectrophoretic force is applied to the nanoparticles in the colloidal solution, causing the nanoparticles to aggregate in the gap. In self-limiting dielectrophoresis that was recently proposed, a capacitance element is connected in series with the nanogap region. When nanoparticles are first assembled in the gap region and the impedance there decreases, most of the applied AC voltage is redistributed to the capacitance element, thereby suppressing further particle assembly in the gap region. In this study, gold nanoparticles were assembled between the drain and source electrodes using self-limiting dielectrophoresis, and the appropriate assembly conditions for single-electron device fabrication were investigated. Furthermore, the electrical characteristics of the fabricated devices were measured in liquid helium (4.2 K) to evaluate their operation as single-electron devices.
