Defect Chemistry and Spectroscopy

The Defect chemistry and Spectroscopy group's aim is to develop multi-scale simulation techniques for point defects and related topics, and to apply them to problems in functional materials design.

Method developments in field ion emission microscopy techniques

The project focuses on development and design of workflows, which enable advanced processing and analyses of various data obtained from different field ion emission microscope techniques such as field ion microscope (FIM), atom probe tomography (APT), electronic FIM (e-FIM) and time of flight enabled FIM (tof-FIM).

Generalized Dipole Correction for Charged Slabs

It is very challenging to simulate within DFT extreme electric fields (a few 10¹⁰ V/m) at a surface, e.g. for studying field evaporation, the key mechanism in atom probe tomography (APT). We have developed a straight-forward scheme to incorporate an ideal plate counter-electrode in a nominally charged repeated-slab calculation by means of a generalized dipole correction of the standard electrostatic potential obtained from fully periodic FFT.
