Public Invitation: Nobel Laureate in Physics Kostya Novoselov visiting Bayreuth University

Return to press releases

University of Bayreuth, Press release No. 141/2019, 7 November 2019

Professor Kostya Novoselov, Nobel Laureate in Physics, will give this year's Otto Warburg Lecture of the Otto Warburg Chemistry Foundation at the University of Bayreuth on 14 November 2019. Media representatives and the public are most welcome! The topic of his lecture in English is the targeted design of new materials based on graphene. He was awarded the Nobel Prize in 2010 for his research into the unusual properties of these extremely thin layers of carbon.

The Otto Warburg Lecture at the University of Bayreuth is an award given annually by the Otto Warburg Foundation to outstanding researchers. In 2011, for example, chemistry Nobel Prize winner Roald Hoffmann, and in 2014, physics Nobel Prize winner Daniel Shechtman were honoured in Bayreuth.


A design kit for new materials on the basis of graphene

Graphene is a two-dimensional material: It consists of carbon atoms, which form a surface of regularly arranged honeycombs, each consisting of six atoms. Thanks to Kostya Novoselov's research, we have learnt that such two-dimensional crystals can exist in isolated cases, and do not necessarily have to be layered on top of each other to form three-dimensional structures. For example, they are contained in the pencil dust that remains on paper that has been written on. Due to its very unusual properties and its broad chemical modifiability, graphene is a very promising material for electronic applications.

In his lecture, the Nobel Prize winner will now show that graphene represents a unique model for the design of completely new materials. In addition to graphene, there are many other two-dimensional materials made up of other elements. These can be obtained by extracting them from three-dimensional, layered crystals, following the example of graphene. However, they can also be reconstructed using graphene as a grid and gradually replacing the carbon it contains with other chemical elements. In this way, a fascinating construction kit for two-dimensional materials with a huge variety of properties is achieved. The conductivity or hardness of such materials, for example, can be extremely varied.

Moreover, the diversity of material properties and their combinations increases exponentially by reassembling the two-dimensional layers into newly assembled stacks. This offers an infinite field of possible combinations. For science, the design of such structures is extremely interesting because they can be used to investigate physical phenomena that have not yet been sufficiently understood - such as the energy spectrum of electrons known as the "Hofstadter's butterfly". Above all, however, this "construction kit" allows the targeted production of new high-tech materials whose combinations of properties make them ideal for technological innovations.
