Kinetics of Fast Crystal Growth in Inorganic Alloys and Molecular Liquids

点击翻译按钮获取中文摘要

The aim of this project is to identify the physical origins of fast crystal growth in three important classes of materials: metallic alloys, chalcogenide alloys and organic molecules. Fast crystal growth is crucial to the development of solid state memory based on phase change. In metallic glasses and many pharmaceuticals, fast growth is a problem, destabilising the desired glassy state. The anticipated outcomes of the project will include the capability to chemically manipulate the crystal growth rate to design new functional phase changes devices, to identify new types of glass forming materials and to replace the 80-year-old theory of crystal growth with one that accurately reflects the microscopic mechanisms of ordering at the growing interface.
