Abstract :

The electronic states in strongly elongated semi-ellipsoidal GaAs quantum dot (QD) in the presence of external electrical field are theoretically investigated within the framework of the geometrical adiabatic approximation. An atypical linear term in the effective confining potential forms a family of non-equidistant sublevels in the electron energy spectrum as a consequence of the specific symmetry of the QD. The possibility of implementation of the electron quasi-continuous spectrum over the lower energy levels through size-quantized Stark effect is also shown.
