RESEARCH SUMMARY

My research is focused on the fabrication and investigation of complex molecular systems with atomic precision. This encompasses the preparation of individual synthetic or biological molecules in an atomically controlled environment on solid surfaces in ultrahigh vacuum using electrospray ion beam deposition (ES-IBD), a preparative mass spectrometry method based on electrospray ionization (ESI). In this environment the atomically resolved imaging of individual molecules and their assemblies by scanning probe microscopy (SPM) is possible (see Figure below). We further employ the unique properties of ES-IBD to fabricate novel, covalently bonded molecular surface coatings by hyperthermal collisions with the surface.
