Micro/nano systems are at the core of numerous established and emerging technologies. This course focuses on the microscopic description of heat transfer and energy conversion. It shows how classical physics laws emerge at larger scales and what unique behaviors are observed at the nanoscale.Content
Part I: Fundamentals (10 weeks)
1. Energy states
- From classical to quantum harmonic oscillators: material waves and energy quantization (wave-particle duality)
- Energy states in solids (Band structure of crystals, Phonons, Density of states)
- Fundamentals of statistical thermodynamics
2. Energy Transport
- Energy transfer by waves (reflection/transmission and tunneling, energy and momentum of electromagnetic fields)
- Particle description of transport processes (Fourier's law, Newton's shear stress and Ohm's law)
3. Energy conversion
- Photon absorption and charge carrier generation
- Dielectric permittivity of materials
4. Liquids and Interfaces (Optional)
Part II: Applications (4 weeks)
In the second part of the course, starting from recent literature results, we will analyze the functioning of selected state-of-the art systems such as thermoelectric devices, plasmonic devices, nanophotonic surfaces for radiative cooling and others.
Keywords
Heat transfer, nanoscale systems, energy conversion
