Papers by Keyword: Interface Potential

Abstract: In this paper a model was proposed to calculate the interface potential of a non ideal finite crystal. Most of the research in this issue usually assume ideal conditions to work with infinite perfect crystals. The model includes a perturbative potential to consider an effect associated to finite size crystal and superficial atomic rearrangement. This effect is considered to be in a first order. The model was applied to graphite , as an example, mainly because of its theoretical interest for wastewater electrochemical treatment.

Abstract: A generalized model of a solid-solid interface is built. The model takes into account additional surface mass densities on both sides of the interface and an anisotropic and/or anharmonic coupling potential. The resonances due to the potential (up to three) manifest themselves by minima (zeros) of transmition and/or extrema in reflected and transmitted waves of different polarization depending on physical properties of the media and of the geometry.
