EFECTO COMBINADO DE PRESIÓN HIDROSTÁTICA Y CAMPOS ELÉCTRICO Y MAGNÉTICO SOBRE LA RECOMBINACIÓN ELECTRÓN-HUECO EN POZOS CUÁNTICOS DE GaAs-(Ga,Al)As.

Using the envelope function method and parabolic bands model, we study the combined electric and magnetic field and hydrostatic pressure effects on the firts confined electron and hole states in GaAs-(Ga,Al)As quantum wells. In this study the electric field is applied in the growth direction of the heterostructure and the magnetic field is parallel to the interfaces. The energy and the corresponding envelope wave functions are calculated developing these last ones through a selected complete set of trigonometrical functions. In particular, we have calculated the energy of the five lower election and hole states as a function of the electric and magnetic field, the hydrostatic pressure, and the width of the well. Additionally, variations of the aluminum concentration in the barrier region, in the direct gap regime, are taken into account. [ABSTRACT FROM AUTHOR]
