Description:
Point defects in diamond, SiC and related materials are promising candidates for quantum information processing, spintronics, and biomarkers applications. In the latter, they are introduced into nanocrystalline materials. Point defects of this kind are created by implantation of dopants and vacancy production. In a tight cooperation with experimental groups of the field, we develop such nanosystems which are biocompatible and can simultaneously realize quantum bits for quantum enhanced sensing.

The candidate’s task is to investigate the structure, stability and electronic, optical as well as magnetic and other physical properties of these point defects in diamond or silicon carbide, relevant for the above topics. The density functional theory quantum mechanical codes at the department can be applied in this research where the computational infrastructure will be available to carry out massively parallel computations. These efforts and studies will be carried out in a wide international network with leading scientific groups all around the world. Results are expected to be published in prestigious journals as well as scientific workshops worldwide including the USA and Asian countries.

Expected skills:
Fundamental knowledge of quantum mechanics and solid-state physics is a must. Working knowledge of UNIX-like operational systems as well as basics of programming languages is also required. Reading English is needed in order to understand literature. Experience with density-functional theory as well as using computational methods is an advantage; not mentioning the ability to working hard and cooperation with colleagues.
