Phonon based condensed matter imaging

该项目将利用在SHeM中对声基化学对比的观察来确定支撑成像机制的物理原理，并利用它们来探测凝聚态成像中的振动过程。成像是发现、应用和制造新材料、新结构和新器件的重要工具。然而，当使用常规显微镜成像时，许多微妙的结构不可逆转地退化和改变。该团队最近发明了扫描氦原子显微镜（SHeM），它可以以纳米级分辨率对表面进行无损成像。他们将使用SHeM来确定支持成像机制的新的基础物理。结果包括将SHeM转变为材料和生物科学家可以在世界各地的实验室中使用的工具。

This project will exploit observations of phonon-based chemical contrast in the SHeM to determine the physics that underpins the imaging mechanism and use them to probe vibrational processes in condensed matter imaging. Imaging is an essential tool for the discovery, application and fabrication of new materials, structures and devices. However, many delicate structures are irrevocably degraded and changed when imaged using conventional microscopy. This team recently invented the scanning helium atom microscope (SHeM), which can image surfaces non-destructively with nanoscale resolution. They will use the SHeM to determine the new fundamental physics that underpins the imaging mechanism. Outcomes include turning SHeM into a tool that materials and biological scientists can use in laboratories worldwide.
