Orbital effects of an in-plane field in a 2DEG quantum dot

ORAL

Abstract

We report on the orbital effects of an in-plane magnetic field on the spectrum of a quantum dot based on two dimensional electron gas (2DEG). We present an effective two dimensional Hamiltonian where these effects enter in proportion to the flux penetrating the 2DEG. We show how the orbital effects allow to extract a wealth of information, e.g., on the heterostructure interface, the quantum dot size and orientation, or the spin-orbit fields. We present experimental data illustrating this new spectroscopic method for quantum dots.
