Introduction to Micro and Nano Scale Energy Transport

As modern electronic devices shrink to the nanometer scale, traditional laws of thermodynamics and heat transfer begin to break down. Understanding how energy moves at the micro and nano scale is critical for designing next-generation semiconductors, thermoelectric materials, and thermal management systems. This course bridges the gap between macroscale heat transfer and nanoscale transport phenomena, equipping you with the foundational knowledge required for modern thermal engineering. You will transition from classical continuum heat transfer to molecular and quantum descriptions of energy carriers, learning how to analyze and predict thermal behavior in extremely small systems. What you'll learn: - Understand the foundational physics of energy carriers, including phonons, electrons, and photons. - Apply the Boltzmann Transport Equation to analyze non-equilibrium thermal transport. - Analyze size effects and boundary scattering in thin films and nanostructures. - Practice calculating thermal conductivity at the nanoscale using kinetic theory. - Explore modern thermal management applications in microelectronics and optoelectronic devices. The course begins with essential terminology, quantum mechanics basics, and statistical thermodynamics, before moving into the specific transport mechanisms of phonons and electrons, and concluding with practical engineering design considerations for microscale systems. This course is designed for engineering students, researchers, and professionals who want to understand nanoscale thermal phenomena, requiring only a basic background in classical thermodynamics and calculus. No prior nanoscale physics experience is necessary. Start reading to unlock the principles of nanoscale thermal engineering today.
