Aarhus Universitets segl

Georgios Pantazidis

I am a PhD student under InterCat working on experimental studies of interstellar reactions on carbonaceous surfaces at Aarhus University

I completed my BSc in Physics with specialization in Solid State and Materials Physics in 2016 and my MSc in Materials Physics in 2018, both at the National and Kapodistrian University of Athens. My studies were experimentally oriented and, while preparing for my thesis, I got involved with research at the Broadband Dielectric Spectroscopy laboratory, under the supervision of Assistant Professor A. N. Papathanassiou.  The research involved spectroscopic studies of mixtures composed by a polymer matrix and dispersed conductive particles, which could be carbon allotropes or other conductive micro and nano particles.

I joined the Surface Dynamics group right after, in February 2018, under the supervision of Liv Hornekær and Andrew Cassidy.

My research

I am part of the EUROPAH-ITN project, which investigates the role of Polycyclic Aromatic Hydrocarbons (PAHs) and related compounds in interstellar environments. In this project, my role is to study the fluorescence properties and stability, of hydrogen and oxygen functionalized C60 molecules on carbonaceous grains. The experimental techniques I use are under ultra-high vacuum (UHV) and involve temperature programmed desorption (TPD), to identify the various species on the surface, scanning tunneling microscopy (STM) to observe, understand and manipulate those species, and x-ray photoelectron spectroscopy (XPS), to determine the different functional groups formed on the carbonaceous surface. I am completing my PhD studies in February 2021.
