We study a microjunction in a two-dimensional electron gas under the action of a uniform magnetic field, orthogonal to the gas plane. The microjunction is modeled as an infinite rectilinear waveguide with parabolic walls interrupted by a barrier. Low

La partie spatiale de la fonction d'onde est calculee exactement pour un effet tunnel dans un champ magnetique confine dans une barriere carree epaisse. A cause du champ perpendiculaire au courant, la transmission est fortement reduite et on observe

We solve exactly and numerically the Schrodinger equation when an atom goes towards a metallic surface in the jellium model. The position of the resonance and its width are discussed in varying the screening of the potential and its distance from the

A realistic model to discuss resonant states in semiconductors as GaAs and InP is developed. Analytic expressions for the energies and the widths of the resonant states are found and compared with recent experimental optical results in InP. Es wird e
