摘要

Recent progress in nanofabrication technologies allows us to access to quantum mechanically well-defined electronic systems, such as quantum dots (QDs) and molecules. Such nanojunctions are expected to open a new paradigm in future optoelectronic devices. We have investigated electron transport through single selfassembled InAs QDs and molecules, using metallic leads with nanogaps. InAs QDs exhibited clear shell filling and novel transport phenomena such as Kondo effect. Furthermore, we have observed current-voltage characteristics molecular junctions fabricated by precisely controlled electromigration technique.
