Research Abstract

The purpose of this research is to observe and control the high-frequency response of semiconductor quantum systems. We focused on transport characteristics of edge-magnetoplasmons (EMPs) in quantum Hall systems, which are charge-density waves traveling along the edge channels. We investigated transmission characteristics of EMPs through quantum point contacts and EMP-cavities and developed some techniques to observe and control the interference of EMPs.
