Extended summary: Nanoscale management of electron-phonon energy transfer

Understanding of nanoscale energy transfer and transformations is of fundamental importance to a variety of technologies, such as chip packaging and energy conversion. Nanostructured materials provide scientists and engineers with many possibilities to manipulate energy transfer and its conversion into various forms. Currently, nanoscale management of energy-related transport and kinetics is mainly associated with engineering of phonons, because these energy carriers have characteristic wavelengths in the nanoscale range.
