Exactly self-similar, and statistically self-similar, features have been studied in the magneto-conductance of an open quantum-dot molecule. The fractal dimensions determined from the two di erent features are found to di er signiΓΏcantly from each other. While we do not understand the detailed origi

Recent experiments have examined the magnetoconductance properties of mesoscopic quantum dots, defined in high mobility GaAs/AlGaAs heterojunctions utilizing split-gate techniques. Here, we report on a submicron, square quantum dot defined in a pseudomorphic InGaAs/GaAs single quantum well through a
We have studied conductance oscillations of a quantum dot by varying the gate potential of one of the gate pairs, that forms the quantum dot, while the other pair was kept at a constant potential. The potential was varied from pinch-off to a level where two or more transverse modes were transmitted
