I investigate electronic superstructures in Van der Waals materials, such as stacking domains in multilayer graphene as well as Charge Density Waves in Transition Metal Dichalcogenides, e.g. TaS2.

 I am specifically interested in Charge Density Waves, a periodic modulation of the local electron density. These influence material properties such as the conduction. They induce phase transitions, sudden changes of material properties as a function of a parameter such as temperature. Reducing the number of dimensions of the system by creating thin layers of material has a strong but unknown influence on the phases, which is our subject of study.

The main measurement tool for our research is the ESCHER Low Energy Electron Microscope (LEEM), with which we are always trying to push the boundaries of what information can be extracted on the atomic and electronic structure of materials. 
In the group of Sense Jan van der Molen I particularly enjoy the mix of challenges posed by the combination of computational data analysis, conversion of raw experimental data to physically meaningful data and the relating of LEEM-data to new physical phenomena.
