Visualization of wave function of quantum dot at Fermi-edge singularity regime

Larkin, Ivan; Khanin, Yu N.; Vdovin, E. E.; Ujevic, Sebastian; Henini, M.

We consider in this work many-body enhanced electron tunneling through an InAs quantum dot in a magnetic field applied perpendicular to the tunneling direction. We have examined in details the anisotropic behavior of the amplitude and shape of the resonant peaks.


Visualization of wave function of quantum dot at fermi-edge singularity regime

Larkin, Ivan; Vdovin, E. E.; Khanin, Yu. N.; Ujevic, S.; Henini, M.

We consider electron tunneling spectroscopy through an InAs quantum dot in a magnetic field applied perpendicular to the tunneling direction. We examine in details the anisotropic behavior of the amplitude and shape of the resonant peaks of I-V curves and concluded that (i) magnetotunneling spectroscopy at FES regime allows establishing position of resonant level in QD with high accuracy. (ii) The distinguishab...
