Item The effect of Cu and annealing treatments on CdS/CdTe heterostructures studied with QE and photocurrent relaxation techniques [Articol](IEEE, 2008) Zhao, H.; Vatavu, Sergiu; Caraman, Iu. M.; Gasin, P. A.; Morel, D. L.; Ferekides, C. S.The photo-emf (photocurrent) decay al light impulses excitation (in longitudinal configuration) has been used to determine the lifetime of the non-equilibrium charge carriers recombining in different regions of the CdS/CdTe Cu containing heterojunction at different temperatures and biases. The photosensitivity spectral distributions have been investigated for samples with different technological variations.
