PhD Student in Applied Physics
Luleå tekniska universitet

- Heltid
The subject comprises physics with an emphasis on calculations and simulations that are closely and widely related to applications and applied research.Project Description
In this project we will extract affordable potentials from expensive DFT results through machine learning (ML) to accelerate nanomaterial growth in MD simulations. Such interactomic potentials are also called force fields (FF). We have developed a ML-FF for carbon and iron that can be used to model the catalytic growth of carbon nanotubes, which we want to extend to include more elements, like hydrogen, oxygen, nitrogen, as well as other metals (copper, nickel, rutenium, platinum) This project involves using DFT to construct datasets of labelled atomic configurations, which will be used to train ML-FFs for MD simulations. Your research will for example target growth mechanisms and fundamental properties associated with nanomaterials. Based on these insights you will predict novel catalysts for controlled growth to achieve better quality products.Duties
As a PhD student you are expected to perform theoretical work within your research studies as well as communicate your results at national and international conferences and in scientific journals. Most of your working time will be devoted to your own research studies. Project planning and independently developing the research topic are also an important part of your work. In addition, you can have the opportunity to teach.The project will focus on performing DFT calculations to construct datasets of labelled atomic configurations used to train ML-FFs for MD simulations. The MD simulations will be used to understand nanomaterial growth in so-called chemical vapor deposition (CVD) with regard to catalyst activity, defect formation and healing, and product steering.Qualifications
You have a Master's degree in engineering physics, physics, chemistry, materials science or a related subject. Your duties require excellent knowledge in at least 1 of the following subjects: computation of nanomaterials, quantum physics, solid state physics, atomic and molecular physics. Experience in atomistic modelling and machine learning is of advantage. Good command of English is mandatory.We are looking for a student who are enthusiastic about modelling and are able to work both independently and as a part of a team. Your project combines materials physics and machine learning and you will work in close collaboration with experts in the field. So good communication skills and the ability to work interdisciplinary are important.Further Information
