- 論文の詳細を見る
We report detection of the edge channel of a two-dimensional electron gas (2DEG) in quantum Hall regime, through the measurement of the chemical potential variation and the compressibility of a 2DEG using a single-electron transistor (SET) on top of the 2DEG@. The measurements at higher frequencies enabled us to detect the incompressible electronic states of the fractional quantum Hall effect (FQHE), the results of which indicate a method for resolving the edge channel of FQHE spatially.
