Strain tuning phonon topology in flexible organic crystals

最近发现了一类可弯曲的有机晶体。这为设计新的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性能。尤其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中都扮演着基本的角色，包括热和电子传导性。通过研究弯曲的单轴应变如何影响材料的振动，利用模拟和实验，该项目将制定策略，以识别、预测和设计适合下一代技术的新的柔性晶体。

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.
