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.
