The opto\u2010electrical method employed is the steady\u2010state photocarrier grating (SSPG), which uses two interfering laser beams to induce a periodic resistivity modulation normal to the sense current lines. We experimentally refined the SSPG, using a double beamsplitter technique and introducing a variable ND filter. We measured diffusion lengths of single GaN and Al<jats:sub>X<\/jats:sub>Ga<jats:sub>1\u2013X<\/jats:sub>N\/GaN double layers, and analysed the obtained diffusion lengths as function of the aluminium concentration, comparing them with the respective drift lengths. Finally, we critically discuss the common interpretation in terms of ambipolar transport. We suggest a new model in which minority carriers are rapidly trapped in acceptor\u2010like valence band tails and participate in the grating blurring passively, as spatially localized recombination centres.
