Time resolved imaging of nanoscale dynamics of gas phase metal particles

气相金属颗粒纳米级动力学的时间分辨成像

基本信息

项目摘要

If macroscopic matter is reduced in size to almost atomic dimensions, many of its properties change dramatically. This is particularly true for structural and electronic properties, and one can therefore expect that also many aspects of motional dynamics will differ substantially from macroscopic behavior. We intend to study how isolated nanoparticles deform or oscillate after a strong excitation. This is presently an almost unexplored field, as no technique was available up to now which couldmonitor the time-dependent shape of a free nanoparticle. We intend to directly image the nanoparticle dynamics for the first time with a novel technique employing time-resolved x-ray diffraction. Ultrashort X-ray pulses from a free electron laser shall be used to measure the time-dependent deformation of the particles after an excitation by a strong optical laser pulse. These „movies“ of the nanoparticle dynamics will not only offer direct access to the elastic properties of the particles and the underlying atomic interactions, but it will also allow one to study how these are changed by a melting of the particles, by a strong electronic excitation, or a high charging. The general atomic structure, the surface morphology as well as the coupling between electrons and nuclei will affect the dynamics. We expect to observe many novel dynamical phenomena which will stimulate research fields far beyond nanophysics.
如果宏观物质的尺寸缩小到几乎原子的尺寸,它的许多性质会发生巨大的变化。对于结构和电子性质来说尤其如此,因此可以预期运动动力学的许多方面也将与宏观行为有很大的不同。我们打算研究孤立的纳米粒子如何在强激发后变形或振荡。这是目前几乎未探索的领域,因为到目前为止还没有技术可以监测自由纳米颗粒的时间依赖性形状。我们打算直接图像的纳米粒子动力学的第一次与一种新的技术,采用时间分辨的X射线衍射。自由电子激光器产生的超短X射线脉冲应用于测量强光学激光脉冲激发后颗粒随时间的变形。这些纳米粒子动力学的“电影”不仅可以直接获得粒子的弹性特性和潜在的原子相互作用,而且还可以让人们研究这些特性如何通过粒子的熔化、强电子激发或高电荷而改变。一般原子结构、表面形态以及电子与原子核之间的耦合都会影响动力学。我们期望观察到许多新的动力学现象,这将刺激研究领域远远超出纳米物理学。
