Wolfgang Theis’s research interests are surface science and its application to nanoscale structures and high-resolution electron microscopy.

He works on the development of instrumentation and processes to grow and anneal thin films, interfaces and embedded clusters on nanoscale-sized (10-100nm) apexes of specially prepared tungsten tips. This is conducted in an ultra-high vacuum (UHV) scanning electron microscope (SEM) with the aim of providing superior samples for transmission electron microscopy (TEM) atomic scale tomography. Similar technology is being developed for thinning and post-processing of focused ion beam (FIB) lift-out pillars in UHV.

This effort is underpinned by ongoing fundamental research in epitaxy and ultrathin film growth dynamics by various surface science methods including low energy electron microscopy (LEEM) and diffraction (LEED).

Dr Theis supervises research in surface- and nano-sciences.
