Electron Diffraction as Tool for Nanoscale Characterization

Dr. Sergi Plana-Ruiz, Crystallography & Mineralogy Unit, Department of Geology, Autonomous University of Barcelone

 Abstract 

Electron crystallography leverages electron diffraction as a physical phenomenon to investigate both the order and disorder in crystalline solids at the nanometre scale. In recent years, advancements in hardware and software for acquiring and processing electron diffraction data have significantly expanded the field’s reach across various scientific disciplines. This seminar aims to provide a general view of two key techniques -3D electron diffraction and 4D-STEM- and highlight their role in tackling complex and concomitant challenges in materials science and nanotechnology. 

 Short Bio/CV 

I am a materials science physicist trained in electron crystallography and electron microscopy. My research focuses on the atomic structure characterization of nanocrystals through the development and implementation of novel and advanced electron diffraction techniques. I use a TEM as an electron diffractometer to understand the crystalline nature of solids at the nanoscale, thus providing fundamental insights that help to explain their physical and chemical properties not attainable by other methods. I am currently a lecturer at the Autonomous University of Barcelona setting up the first Spanish group dedicated to the advancement of electron diffraction methods.
