PhD position at NTNU – Nanoscale magnetic imaging using 4D-STEM
A PhD position is available at the Faculty of Natural Sciences and Technology (Department of Physics) of the Norwegian University of Science and Technology (ESTEEM3 partner). Deadline for application: 30th April 2020.
Description
The aim of this project is to use scanning transmission electron microscopy (STEM) combined with the new type of fast pixelated electron detectors to do 4D-STEM to study both the crystal and magnetic domain structure at nanometre length scales. This will be done using STEM-differential phase contrast (DPC) in co-junction with scanning precession electron diffraction (SPED), both utilising “big data” processing methods. These techniques will be combined with in-situ heating, cooling and the application of external fields over the specimen. This will effectively create an experimental “nano lab” not only for advanced analyses of magnetic materials, but also as a test bed for solid state magnetic theory.
As the 4D-STEM technique is a recent and ongoing development, much of the work will involve development and implementation of data processing software using scientific Python, the development of new and improved ways of analysing magnetic properties and structure at the nanoscale. The work will be done at the TEM Gemini Center/NORTEM Trondheim node and in collaboration with the Center for Quantum Spintronics (QuSpin), the Functional Materials and Materials Chemistry (FACET) Research Group, and the Nanoelectronics and Photonics Research Group at the Department of Electronic Systems at NTNU.
Requirements
The PhD-position's main objective is to qualify for work in research positions. The qualification requirement is that you have completed a master’s degree or second degree (equivalent to 120 credits) with a strong academic background in physics, nanotechnology, material science or equivalent education with a grade of B or better in terms of NTNU’s grading scale. If you do not have letter grades from previous studies, you must have an equally good academic foundation. If you are unable to meet these criteria you may be considered only if you can document that you are particularly suitable for education leading to a PhD degree.
We are seeking a person with a good experimental background, experience in materials characterization and scientific programming. Applicants with prior documented experience in electron microscopy, and TEM in particular, are preferred. Knowledge and practical experience with data processing using scientific Python, especially HyperSpy, and theoretical or experimental experience with magnetic materials are also desirable.
