Explore the dispersion relation in quantum transport through this 21-minute lecture from the nanoHUB-U course "Fundamentals of Nanoelectronics Part B: Quantum Transport" by Supriyo Datta. Delve into advanced concepts in non-equilibrium statistical mechanics as they apply to nanoelectronics, building understanding of how current flows on an atomic scale within nanotransistors that contain active regions barely a few hundred atoms long. Learn how the same technology enabling modern smartphones with billions of nanotransistors has led to deeper insights into atomic-scale electrical phenomena. Examine fundamental conceptual issues related to resistance at the atomic level, the interconversion of electricity and heat, thermodynamic principles, and the relationship between information and energy. This lecture assumes background knowledge of linear algebra and differential equations while making advanced nanoelectronics concepts accessible to students across various branches of science and engineering.
