Abstract
In this thesis we study a state of the art inline electron holography technique, titled Full Resolution Wave Reconstruction (FRWR). A rewiev of the reconstruction algorithm is given. We have tested the FRWR capabilities to recover the mean inner potential of Cu2O, and the potential profile across a Cu2O/CuO/ZnO heterojunction.In addition the effects of experimental setup such as objective aperture and energy filtering have been investigated. In addition, theoretical values of the mean inner potential have been calculated from following two different models, a non-binding atom model and an ionized atom model.
