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类别的快速晶体生长的物理起源：金属合金，硫醇化合物合金和有机分子。快速晶体生长对于基于相变的固态记忆的发展至关重要。在金属眼镜和许多药品中，快速生长是一个问题，破坏了所需的玻璃状态。该项目的预期结果将包括化学操纵晶体生长速率以设计新功能相变设备的能力，以确定新型的玻璃形成材料，并替代80年历史的晶体生长理论，从而准确地反映了在生长界面处的订购界面的微观机制。
