Abstract
We generalized the theory behind the light-induced grating (LIG) electro-motive force (EMF) technique for material characterization and interferometry, first introduced by Petrov et al.1 In particular, we have accounted for the screening length, Ls, that allowed us to describe adequately the dependence of the amplitude, Jmax, and the decay-time, τR, of the electric current versus the grating period, L, and determine correctly the diffusion length, Ld, and the screening length, Ls for the current carriers.
