X12 - Transmission Electron Microscopy and Spectroscopy from First Principles

Sunday, July 28, 2024

8:30 AM - 5:00 PM US EST

Location: 25C

Simulations of transmission electron microscopy images and electron energy-loss spectra can not only be vital for correctly interpreting and understanding measured data, but may also be used to design experiments or even instrumentation. With modern open-source tools, simulations of all kinds of image signals including HRTEM, ED, DPC and 4D-STEM are easy to learn and tractable on a personal computer. Computational exercises are performed using the open-source Python package abTEM. Simulation of electron energy-loss spectra is more demanding, and requires specialized expertise and high-performance computing resources. Different approaches to model phonon, plasmon and core-loss spectra are introduced.

Topics to include:

(Scanning) transmission electron microscopy image simulations

Introduction to open-source TEM simulation software

Computational exercises for modeling common imaging modes

First-principles simulation of electron energy-loss spectroscopy

Introduction to principles of phonon, low-loss and core-loss modeling
