Kinetics of Fast Crystal Growth in Inorganic Alloys and Molecular Liquids

该项目的目的是确定三类重要材料快速晶体生长的物理来源：金属合金、硫化物合金和有机分子。快速晶体生长对相变固态存储器的发展至关重要。在金属玻璃和许多药品中，快速增长是一个问题，破坏了理想的玻璃化状态。该项目的预期成果将包括用化学方法控制晶体生长速度、设计新的功能相变装置、识别新类型的玻璃形成材料以及用准确反映生长界面有序化微观机制的理论取代已有80年历史的晶体生长理论。

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.
