Prof. Sebastiaan Van Dijken (born 1973) defended his doctorate at University of Twente in the Netherlands in 2000. After that he worked as a researcher at the IBM's Almaden Research Center in San Jose, U.S., at Trinity College in Ireland and at the VTT Technical Research Centre of Finland in its nanotechnologies and microsystems unit.

In the first part of the talk, I will discuss our low-temperature STM experiments on molecules on hexagonal boron nitride (h-BN) on Ir(111). h-BN acts as ultrathin insulating layer for organic molecules, while simultaneously templating their self-assembly [1]. Tunneling spectroscopy experiments on cobalt phthalocyanine (CoPC) reveal narrow molecular resonances and indicate that the charge state of CoPC is periodically modulated by the h-BN moiré superstructure.
