Thermal Physics of Nanosystems
Теплофизика наносистем
Course Overview
This course offers a systematic exploration of thermal physics at the nanoscale. It integrates classical continuum theories with cutting-edge atomistic simulations to explain heat transport mechanisms in solids.
Students will master the theoretical framework of Lattice Dynamics and Phonon Transport, while developing practical skills in First-Principles Calculations. By the end of the course, students will be proficient in calculating phonon spectra, density of states, and thermal conductivity for bulk and low-dimensional materials using industry-standard computational tools.
