Abstract
The PME effect in an inhomogeneous semiconductor is calculated assuming uniform local mobilities. An experiment is described in which a gapβgradient is induced in a germanium crystal by means of a pressure gradient. The result is consistent with previously measured values of the pressure dependence of the energy gap.

We have calculated the photo-emf in square profile graded band-gap semiconductor structures under local illumination. It is shown that the photo-emf is a linear function of the position of a light strip on the photosensitive surface and it changes the sign when the light strip passes across the cent
