Learn about pseudo-spins in quantum transport through this 25-minute lecture from the nanoHUB-U course "Fundamentals of Nanoelectronics Part B: Quantum Transport" by Supriyo Datta. Explore advanced concepts in non-equilibrium statistical mechanics as they relate to atomic-scale current flow, building on the foundation of quantized conductance and ballistic transport. Discover how pseudo-spin concepts apply to nanoelectronic devices where active regions span just a few hundred atoms, connecting fundamental quantum mechanical principles to practical nanotransistor technology. Examine the theoretical framework that underlies modern smartphone technology enabled by billions of nanotransistors, while addressing conceptual issues related to resistance on an atomic scale and the interconversion of electricity and heat.
