Abstract :
Here we will present a novel method of forming QD based on the lateral confinement on QW by electrical field. The electrical field would deplete the QW into a very small region, forming a "quantum disk". The field induced lateral confinement combined with the vertical confinement of the QW would form a three dimensional confinement.
