Mesoscopic description of boundary effects and effective thermal conductivity in nanosystems: Phonon hydrodynamics

Nanometer-sized devices are of considerable current interest in micro/ nanoelectronics wherein the adjective “smaller” has meant greater performance ever since the invention of integrated circuits: more components per chips, faster operations, lower costs, and less power consumption. Miniaturization is also the trend in a range of other technologies, as for example, optics, catalysis, and ceramics. Many active efforts are currently observing in information storage, too, in order to develop magnetic and optical storage components with critical dimensions as small as tens of nanometers.
