    PhD studentship in the Computational Structure Prediction of Energy Materials
    Oleh : Birmingham Univ
    Selasa, 28 November 2017 (13:18 WIB) dari IP 203.160.128.134

    A 3-year UK/EU PhD student-ship is available in the group of Dr Andrew J. Morris who has recently relocated to the School of Metallurgy and Materials at the University of Birmingham, UK.

    The research group, currently comprising 6 graduate students with 3 post-doctoral fellows, uses first principles techniques to predict the structure and properties of materials for energy technologies.

    The creation of new materials is both difficult and expensive. It is very difficult to “see” the structure of these materials over the length scales that they work and very expensive to create prototype materials to test. Whilst experimental physics can use X-rays, high-energy electrons or neutrons to infer the structure of these materials, this inference is made much more robust when combined with theoretical predictions of the kinds of structures that can be formed. In a computer we use quantum mechanical calculations to simulate the results of these kinds of experiments, helping to understand materials and suggest new materials with the kind of properties desired.

    Our recent interest has been in electrodes for lithium-ion batteries [1]; novel charge carriers (beyond-Lithium) for batteries, such as sodium[2]; solid-state electrolytes[3]; and nano-phase change materials [4]. To do this, we use density-functional theory and global search techniques carrier out on the group's supercomputer along with university, regional and national supercomputers. We work closely with world-leading experimental groups to verify our predictions and aid further experiments. More details about the group may be found at: http://www.andrewjmorris.org

    The project is anticipated to be a mix of code development, high-throughput computation and liaison with experimental collaborators. The precise project can be tailored somewhat to taste.

    The candidate will have a 1st class Undergraduate or Masters degree (or equivalent) in Physics, Chemistry, Materials Science or related discipline. A strong background with programming (e.g. python, Fortran0X, C, C++), solid-state materials or electrochemistry would be advantageous.

    Applications must be made through the university's on-line application system[5]: please provide a cover letter summarising your research interests and suitability for the position; the contact details of two people able to provide a letter of reference; and a full curriculum vitae. Please also send a copy of your full application to Andrew Morris directly.

    Closing date for applications Friday 12th January 2018.
