Abstract
A new photoelectromagnetic effect is described, in which the short-circuit current is proportional to the difference in surface recombination velocities of a pair of parallel surfaces. The surfaces are the planes of a slab which is illuminated in the direction in the presence of a magnetic field in the same orientation. In addition to the primary diffusion of the generated carriers along , there ensues a secondary flow in the transverse direction. If the boundary conditions at the two planes are not identical, there results a net flow of carrier pairs toward one of these surfaces. The magnetic field deflects these carriers, and a net short-circuit current passes in the direction. Measurement of this current affords a means of probing the surfaces from the interior of the sample. The theory of the effect and its experimental observation are described.
