Explore topological insulators in this 20-minute lecture from the nanoHUB-U course "Fundamentals of Nanoelectronics Part B: Quantum Transport" taught by Supriyo Datta. Discover how modern smartphones rely on billions of nanotransistors with active regions spanning just hundreds of atoms, and learn how this technology has deepened our understanding of atomic-scale current flow. Examine the unique properties of topological insulators as materials that conduct electricity on their surfaces while remaining insulating in their bulk, and understand their significance in quantum transport phenomena. Gain insights into advanced concepts in non-equilibrium statistical mechanics through accessible explanations that connect quantized conductance principles to practical nanoelectronic applications, requiring only basic knowledge of linear algebra and differential equations.
