Digital Electron Diffraction
Computer control of electron microscopes, digital image processing, and the capability of modern PCs to capture and analyse large datasets are opening up a new world of opportunity for analysis of materials at the nm scale. At Warwick we have recently used automated collection and combination of many hundreds of individual electron diffraction patterns with different incident beam orientations to produce new types of data set. These new datasets show an astonishing level of intricacy and detail. This kind of data gives a direct window into materials properties such as symmetry and structure, and even allow quantitative measurements of details such as the bonding electron distributions in the material.
In this project you will be part of a team developing computer code to control electron microscopes and data capture systems. You will use the new techniques that you create to study materials and obtain understanding which cannot be gained with existing analysis techniques. The range of materials which can be studied is large, but there is particular interest in studying phase transformations in-situ in the electron microscope.
This work is associated with an EPSRC-funded project and there are several established collaborations which will provide materials for study.
A full 3.5 year studentship for UK students (fees and maintenance) is available, and may be available to outstanding EU applicants. Candidates should hold or expect to hold a 1st (or high 2.1) in Physics or related subject area. See http://www2.warwick.ac.uk/fac/sci/physics/prospective/postgraduate/pgintro/projects/priority/ for further details.
The Physics department is proud to be an IOP Juno Champion and a winner of an Athena Swan Silver Award, reflecting our commitment to equal opportunity and to fostering an environment in which all can excel.
