✦ Synopsis

We investigate the existence of a band structure in GaAs/Al x Ga 1-x superlattices with cylindrical symmetry, namely GaAs/Al x Ga 1-x As cylindrical superwires. These systems consists of a large number of concentric GaAs and Al x Ga 1-x As alternate cylindrical shells around a central GaAs cylindrical wire. Despite the radial configuration (that breaks the translational symmetry) and the electron confinement in the central three-dimensional well, a band structure can emerge depending on the number and thickness of the cylindrical shells.

A GaAs/Al x Ga 1-x As heterointerface contains charge traps, which can capture and emit a single electron stochastically. We study random telegraph signals (RTSs) from these traps using a single electron tunneling (SET) transistor formed in the heterostructure. The output of the SET transistor switc

We study inhomogeneous doping effects on the confinement properties of modulationdoped single nonabrupt GaAs/Al x Ga 1-x As quantum wells. We describe the inhomogeneous doping using error function profiles, and we solve self-consistently the coupled Schrödinger (with a position dependent kinetic ene
