stillingsbetegnelse: PhD scholarship in Theoretical Nanotechnology

jobbeskrivelse:
The rapid development in nanofabrication techniques in recent years has made it realistic to nanostructure graphene to tailor its properties for specific applications. One particular way to nanostructure graphene is to dope it selectively: experiments have shown that under certain conditions substitutional doping occurs very asymmetrically with regard to the two sublattices which form the graphene lattice. This opens many new ways to fine tune graphene’s electronic transport properties. The aim of the PhD project is to simulate and study, theoretically, the properties of asymmetrically doped graphene, and other novel two-dimensional materials (phosphorene, boron nitride, transition metal dichalcogenides, etc). We aim to explore the new concept of “doping-profile engineering”. Particular focus needs to be paid to disorder, and computationally efficient simulations techniques are needed because the low concentration of dopands necessitates the consideration of systems consisting of millions of atoms. A possible theoretical approach is the “patched Green’s function technique”, which has recently been developed at DTU Nanotech. Responsibilities and tasks The PhD project will involve developing and implementing methods for studying nanostructured graphene with a large number of dopand atoms. This includes large-scale numerical methods for calculation of the conductivity of disordered structures with several millions of atoms. The methods will be used to study the properties of selectively doped graphene in external fields, with a focus on fundamental properties as well as possible applications. Ultimately the project should lead to suggestions for experiments, to be carried out by colleagues at DTU Nanotech. The position requires a strong background in theoretical solid state physics, preferably with experience in implementing tight-binding models and methods capable of handling very large-scale systems. Knowledge and experience with a programming language capable of high-performance numerical simulations is required. Qualifications Candidates should have a master's degree in engineering or a similar degree with an academic level equivalent to the master's degree in engineering. Approval and Enrolment The scholarships for the PhD degree are subject to academic approval, and the candidates will be enrolled in one of the general degree programmes of DTU. For information about the general requirements for enrolment and the general planning of the scholarship studies, please see the DTU PhD Guide. Assessment The assessment of the applicants will be made by Professor Antti-Pekka Jauho and Postdoc Stephen Power. We offer We offer an interesting and challenging job in an international environment focusing on education, research, public-sector consultancy and innovation, which contribute to enhancing the economy and improving social welfare. We strive for academic excellence, collegial respect and freedom tempered by responsibility. The Technical University of Denmark (DTU) is a leading technical university in northern Europe and benchmarks with the best universities in the world. Salary and appointment terms The salary and appointment terms are consistent with the current rules for PhD degree students. The period of employment is 3 years.
