Phonon based condensed matter imaging

这个项目将利用SHEM中基于声子的化学对比度的观测来确定支撑成像机制的物理原理，并使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，许多微妙的结构在使用传统显微镜成像时会不可挽回地退化和改变。这个团队最近发明了扫描氦原子显微镜(SHEM)，它可以以纳米级的分辨率无损地成像表面。他们将使用Shem来确定支撑成像机制的新的基础物理学。成果包括将Shem变成材料和生物科学家可以在世界各地的实验室使用的工具。

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.
