摘要:
材料的变形与相变、晶体生长、电荷分离传输、催化反应等过程均涉及到材料中的界面问题,并且紧密依赖于界面附近的原子和电子结构。因此,可以通过调控材料的界面原子、电子结构来赋予材料特殊的新功能。介绍了材料界面研究的最新进展,枚举了研究者如何获得固-固材料界面的原子结构,在光催化和太阳能电池中如何利用界面分离和电荷传输及电子全息技术定量分析二维电子气,以及在材料生长和催化过程中的固-液和固-气界面演化。这些研究结果展示了人们对界面原子、电子结构前所未有的认知,这些科学而直观的构效关系对于启发研究者设计和构筑更加精细、高效的界面结构提出了新思路。
Abstract:
The progresses such as mechanical deformation and phase transition, crystal growth, charge separation and transportation, catalysis are basically interface problems in materials. These interface phenomena depend on the atomic configuration and electronic structure at interfaces. Accordingly, we can endow the materials specialized functions by design the interface structures at atomic and electronic scale. In this brief review, three interfaces, solidsolid, solidliquid and solidgas are discussed. New research progresses on interface of materials, including the atomic structure characterization, the interface application on charge separation in photocatalysis and solar cell, visualization and quantification of 2D electron gas using inline electron holography, the evolution of interface during materials growth and catalysis are introduced. These new findings show an unprecedented knowledge on the atomic structure and electronic structure of material interface. The structure and property relationship was revealed directly and would inspire creative works to design more complex and efficient material interfaces.
