Matter

- Successfully captured real-time atomic-scale degradation of perovskite materials caused by water. - Identified degradation mechanisms based on differences in degradation rates across crystal facets, and proposed strategies to enhance perovskite stability. - Research findings published in Matter, a prestigious journal in the field of materials science.

A recent research led by City University of Hong Kong (CityU) has discovered that the ultrathin gold nanoribbons with unique hexagonal (4H type) crystal phase shows “liquid-like” behaviour under heating, but its hexagonal crystalline structure remains stable. This provides insight into the thermal stability of this new type of metallic nanomaterials and facilitates the development of practical applications in the future.
