Self-similarity in the low temperature magneto-transport in a single quantum dot

摘要

Self-similar conductance fluctuations has been studied by the lowtemperature magneto-conductance in order to clarify the fractal transport insingle quantum dot. We have observed a clear three-hold or four-foldself-similar structure in the magneto resistance. In our discussion based oncoherent properties of electron waves in the dot, we can examine such aself-similar property by using experimental determinations of phase brakingtime and phase coherent area.
