Topic: Carbyne by definition is an infinite linear chain of carbon atoms that forms the truly 1D allotrope of carbon. Exploring carbyne and its properties has long been hindered by its extreme chemical instability. This obstacle has been overcome in 2016 with the synthesis and stabilization of individual carbyne chains comprising of thousands of atoms confined inside carbon nanotubes.  In this talk, I will present our recent studies on individual confined carbyne chains by Raman spectroscopy, i.e. how the nanotube host influences the properties of carbyne. We will explore how confined carbyne may test advanced concepts of light-matter interaction, illustrate current limitations in the field, and provide an outlook on future directions.

CV: Sebastian Heeg obtained his diploma and PhD in Physics in the group of Stephanie Reich at Freie Universität Berlin. After PostDocs at the University of Manchester with Aravind Vijayaraghavan, ETH Zürich with Lukas Novotny, and again Freie Universität Berlin with Kirill Bolotin, he started his Emmy Noether Junior Research Group at Humboldt Universität zu Berlin in 2021. Sebastian is interested in studying low-dimensional solid-state systems like 2D semiconductors and one-dimensional atomic chains with optical spectroscopy, with a focus on plasmon-enhanced and tip-enhanced Raman spectroscopy.

Following the lecture, there will be a get-together where participants can exchange ideas with each other over pizza and drinks in the Remise and the garden of the Magnus-Haus.

The event is sponsored by the Wilhelm and Else Heraeus Foundation.
