My expertise in surface science and in particular my research activities related to understanding and controlling reactions in molecular ices induced by electrons, as well as reactions at surfaces and interfaces induced by atomic species will help shed light on how complex molecules are formed in ultra-cold interstellar space. The experiments will be performed using a Createc type LT-STM setup situated at the Interdisciplinary Nanoscience Center (iNANO).
At InterCat I will design and perform cryogenic (4.2 K) scanning probe microscopy (SPM) experiments. The SPM studies are aimed at providing detailed information at the nanoscale about chemical reactions occurring between molecules such as PAHs, H2O, NH3 etc. adsorbed on surfaces.
These reactions will be activated by the presence of nanoparticles and/or driven by bombardment with atomic radicals (H, O), electrons and photons under conditions that mimic those in interstellar space. All measurements will be performed in-situ using a LT-STM setup retrofitted with electroluminescence capabilities for optical studies in the VIS-NIR spectral range of light.
I plan to expand the spectral range of the setup towards UV light (up to 7-8eV) for studying reactions occurring in interstellar regions under the influence of intense UV light radiation.
