A theoretical analysis of quantum-wire fabrication by vacancy-enhanced interdiffusion of quantum wells

The fabrication of quantum-wire structures using vacancy enhanced interdiffusion of quantum wells is analyzed theoretically. A phenomenological equation is used to describe the effects of strain on vacancy diffusion. The quantum-wire confinement potentials are studied as a function of the trench opening widths and the separation distances from the SiO/sub 2/-AlGaAs interface. The lateral confineme...
