Abstract
The problem of measuring very steep doping profiles, of the type usually present in ion-implanted GaAs FETs, is critically examined in the light of numerical solutions of the Poisson equation for some typical layers. It is found that the most popular techniques (C/V and saturation-current measurements) may be quite misleading or, at least, appreciable corrections are typically required.
