ZnO compounds thickness-related optimality on bases of blue-redshifts and Urbach tailing

Author(s): A.Amlouk, K.Boubaker, M.Amlouk

In this study, the spray pyrolysis system has been selected to grow ZnO crystals of different thicknesses. The existence of a critical thickness has been already conjectured on the bases of optothermal and mechanical investigations. Energy levels shifts within ZnO forbidden band along with Urbach tailing perturbed evolution have been analyzed in order to explain and justify the already conjectured thickness-related optimality.
