We report the results of theoretical studies of the electronic properties of laterally confined electron systems in semiconductor heterostructures. The finite harrier effect is considered under the quasi-decoupled approximation. The side lengths are characterized by L x (L y ) >> L z . The effects of applied external electric and magnetic fields are considered. The evolution from the electrical confinement to magnetic confinement is discussed in detail for the quantum dots. Finally, we study the electronic structure of a quantum wire presenting a lateral constriction.
