“Packing Electrons in a Nano Box: Control of Many-Body Correlation by Quantum Confinement”


National Institute for Materials Science

Abstract

A team headed by Dr. Takashi Kuroda, Senior Researcher, and Dr. Marco Abbarchi, Researcher, of the Quantum Dot Research Center (Managing Director: Kazuaki Sakoda), National Institute for Materials Science (President: Sukekatsu Ushioda), in joint research with Hokkaido University, succeeded in controlling the few-particle quantum state of a semiconductor quantum dot, and changing its correlation energies. This research achievement will make it possible to develop semiconductor non-linear devices which enable stable drive with low power consumption.
