材料界面是材料组织的重要组成部分,对能量传递与物质传输起着重要作用,直接影响着材料的应用范围。随着当今材料科学向纳米尺度等低维领域发展,材料的宏观性能越来越依赖于原子尺度的超微观结构,尤其与表面、界面的性质休戚相关。研究材料界面、超微观结构与成分之间关键规律的重要性也日益凸显。在球差校正电子显微束、热电力等外场作用下的原位分析、电子显微束和原子尺
Material interface is an important part of the material organization, plays an important role in energy transfer and material transfer, which directly affects the material’s application range. With the development of materials science to low-dimensional fields such as nanoscale, the macroscopic properties of materials depend more and more on the atomic-scale microstructures, especially the surface and interface properties. The importance of studying the key rules of materials interface, ultrastructure and composition has also become increasingly prominent. In-situ analysis of spherical aberration-corrected electron microscopy, thermal power and other external fields, electron microscopy and atomic ruler
