Electron Bunching in Transport Through Quantum Dots in High Magnetic Field
arXiv:cond-mat/0607756 · doi:10.1103/PhysRevLett.98.066801
Abstract
Shot noise measurements provide information on particles' charge and their correlations. We report on shot noise measurements in a ubiquitous quantum dot under a quantized magnetic field. The measured noise at the peaks of a sequence of conductance resonances was some nine times higher than expected; suggesting bunching of electrons as they traverse through the dot. This enhancement might be mediated by an additional weakly coupled level to the leads or an excited state. Note that in the absence of magnetic filed no bunching had been observed.
