Benjamin Walter asked himself the fundamental question of whether it is possible to synthesize graphene with coronene - an organic molecule - on a germanium surface. Graphene is a semiconductor with a promising future that could revolutionize electrical engineering in 50 years' time. The 16-year-old student conducted his research using scanning tunneling microscopy. Although he was able to show that graphene production is not possible, he gained relevant information about the geometric and energetic aspects of the interaction between molecule and substrate. With this project, he was the national winner in the field of physics and received an invitation to the 23rd European competition for young researchers.
