摘要
Electron states and tunneling properties of two vertically coupled quantum dots are analyzed. The energy mismatch of the dots affects the phase diagram as a function of the quantum mechanical coupling and magnetic field normal to the plane. A magnetic field parallel to the barrier mixes the single particle states and also induces a singlet-triplet transition. (C) 2000 Elsevier Science B.V. All rights reserved.
