Fundamental study of heat transport by phonons and electrons in semiconductors at micro and nanoscale

The advancement of nanotechnology has enabled the miniaturization of electronic components to the extent of several nanometres, thus leading to heat dissipation issues which often result in device failure. This thesis involves a fundamental study on phonon and electron transport in semiconductor materials commonly used in electronic components. It proposes Monte Carlo phonon and electron transport simulation models to stochastically capture the physics of the transport mechanisms. Such information is essential to facilitate the study of heat distribution in sophisticated electronic devices in order to ensure optimum device performance and to prolong the device life.
