Controlling the properties of 2D materials by defect engineering and atomic scale characterization by scanning tunneling microscopy

In this project, we will use scanning tunneling microscopy and spectroscopy (STM/STS) operating under ultra-high vacuum and at low temperature to study the structure and electronic properties of generated defects in 2D materials at the atomic scale. Substitutional atoms (such as nitrogen in graphene), vacancies and other defects will be used to tune the properties of the materials in order to reach new functionalities (see Figure). The impact of defects on the density of states will be investigated at the atomic scale by STM/STS. The interaction of defect sites with adsorbed molecules will be probed as well to reveal the impact of the defects on the chemical activity. Ab-initio calculations will be utilized to provide insight into the experimental outcomes.
The candidate must have a good knowledge and practice of scanning tunneling microscopy  in ultrahigh vacuum. A background in ab initio calculations will be appreciated.

The starting of the position will be during the year 2024 for a duration of up to 18 months.
