Analysis of magnetoresistance data in terms of the tight-binding model reveals that not only electron concentration and mobility have been increased by illumination, but also the coupling among 2D electron layers in neighboring quantum wells has been reduced
Z měření magnetorezistence vyplývá, že perzistentní fotovodivost nejen zvyšuje koncentraci elektronů, ale rovněž snižuje vazbu mezi sousedními kvantovými jámami v supermřížce
