A class of organic crystals have been recently discovered that are bendable. This opens an exciting opportunity to design new functional materials but requires a detailed understanding of how bending affects material properties. Of particular importance is to identify how bending affects the vibrational behaviour of the material, because these vibrations play a fundamental role in nearly all functional properties, including thermal and electronic conductivity. By studying how the uniaxial strain of bending affects material vibrations, using both simulation and experiment, this project will develop strategies to identify, predict, and design new flexible crystals suitable for next-generation technologies.

最近发现了一类有机晶体可弯曲的。这为设计新功能材料提供了一个令人兴奋的机会，但需要详细了解弯曲如何影响材料特性。特别重要的是确定弯曲如何影响材料的振动行为，因为这些振动在几乎所有功能特性（包括热和电子电导率）中都起着基本作用。通过使用模拟和实验研究弯曲的单轴菌株如何影响材料振动，该项目将制定策略来识别，预测和设计适合下一代技术的新柔性晶体。
