报告摘要:

With rapid advance in material technology, material design has been required to rely on more fundamental principles. Intrinsic properties of materials are largely governed by their electron behaviour, which determines the atomic bond strength and characteristics. Great effort has long been made to correlate properties of materials to their electron state based on quantum mechanics. However, quantum theories are generally complicated to be used in material design, especially for structural materials which consist of various phases and imperfections. Thus, it is highly desired to have simple but fundamental parameters, which largely reflect the electron behaviour of materials, for material analysis and design in a feasible manner. In this talk, electron work function, which is the minimum energy to move electrons at Fermi level inside a solid to its surface without kinetic energy, is demonstrated to be a promising indicative parameter to characterize materials and provide clues for material design and modification. Correlations between EWF and mechanical, electrochemical and tribological properties of materials will be demonstrated and discussed.
