Electrons sometimes behave as particles, and sometimes as waves. Both aspects are used when investigating nano-structures with electron beams. In this research program we design and perform experiments to measure sample composition using the particle nature, and the atom positions by using the wave nature of electrons. These novel experiments, using unique spectrometers designed and developed in Australia, are aimed at making new forms of electron microscopy possible, but will also result in a better understanding of existing electron microscopies and synchrotron-based measurements.

电子有时表现为粒子，有时表现为波。这两个方面都用于调查纳米结构与电子束。 在本研究计划中，我们设计并执行实验，利用粒子性质测量样品成分，并利用电子的波动性质测量原子位置。这些新的实验，使用独特的光谱仪在澳大利亚设计和开发，旨在使新形式的电子显微镜成为可能，但也将导致更好地了解现有的电子显微镜和基于同步加速器的测量。
