Abstract
We discuss the possible analysis of an electron distribution obtained by capacitance-voltage profiling for the determination of the conducti on band offset of a single quantum well. We show that, for this method which requires only relatively light experimental equipment, a noncon suming computational time interpretation can be set up within a quite satisfactory degree of accuracy. As an application, we report the stud y of a lattice matched InP/Ga0.47In0.53As/InP quantum well for which w e get Delta E(c) = (200 +/- 10) meV, in good agreement with ether meas urements upon this system.
