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.

该项目的目的是确定三种重要材料中快速晶体生长的物理来源：金属合金，硫属化物合金和有机分子。快速晶体生长是发展基于相变的固态存储器的关键。在金属玻璃和许多药物中，快速生长是一个问题，会使所需的玻璃态不稳定。该项目的预期成果将包括能够通过化学方法操纵晶体生长速率来设计新的功能相变装置，识别新型玻璃形成材料，并用准确的理论取代已有80年历史的晶体生长理论。反映生长界面有序的微观机制。
