This video is Konstantin Novoselov's Nobel Lecture in Physics from 2010. He discusses the discovery of graphene, its unique properties, and potential applications. The lecture covers the history of carbon allotropes, the challenges in creating two-dimensional materials, the methods used to produce graphene, its unusual electronic and optical properties, and its wide-ranging applications, from electronics to displays.
Konstantin Novoselov focuses on three key points in his lecture regarding graphene:
Graphene differs from typical conductive materials because it possesses a chiral symmetry between electrons and holes, meaning positively and negatively charged particles are symmetric. In contrast, most conductive materials have charge carriers that are either predominantly positive (holes) or negative (electrons).
The analogy used to explain this difference is the political landscape of countries.
The lecture mentions several existing and potential applications of graphene:
