Interfacial Free Energy of Copper: Experimental and Computational Approaches

250304 Department of Computer Science & Engineering Interfacial Free Energy of Copper: Experimental and Computational Approaches Knowledge of interfacial free energy is of major importance for theoretical, computational, and practical applications such as developing bio-compatible materials, colloids, optical devices and metal-matrix composites. There is no universally reliable and convenient method to perform experimental determination of solid-solid interfaces. There are computational methods, and direct and indirect experimental methods. In this study we will overview the major methods for solid copper. We will be introducing atomic force microscopy (AFM) as a new method. AFM will be compared to zero-creep and optical interferometry methods, as well as the outcomes of computational models in terms of ease of use, cost, time, resolution of the technique, and accuracy of the results. Our results on sample preparation for dihedral measurements with the AFM will be shared and discussed.
