Abstract

I will talk about the recent progress for single-electron transistors (SETs) fabricated by bottom-up strategy, which is the result of my research group in Japan. Stable operation under room temperature, controlled characteristics, and mass-production are required for SETs toward practical application. Bottom-up fabrication processes can overcome these issues because the structure can be controlled in sub-nm scale to utilize molecular self-assembly and chemical processes. Our group has demonstrated “Chemically assembled SETs” to assemble three nano-components: Self-assembled monolayer, Synthesized Au nanoparticles, and Electroless Au plated nanogap electrodes [1-3]. In this presentation, I will show the detailed electrical characteristics of chemically assembled SETs and the previous research collaboration with SP group. [1] Appl. Phys. Lett. 100, 033101 (2012).
