We show that with a Full-Band dispersion, the specific heat is closer to the experimental value than with an isotropic quadratic dispersion. So we use a Full-Band dispersion in the transport algorithm. A Monte Carlo algorithm has been developed to simulate phonon transport in silicon nanowire. It has been successfully used to simulate the thermal conductivity.
We present for the first time multi-scale modeling of self-heating effects in conventional MOSFET devices in a common-source and common-drain configurations in which one of the devices is the device under test (DUT) and the other device is the sensor. Via comparisons to experimental measurements performed at IMEC, we are able to uncover the temperature of the hot spot. This is also the first study...
We present a quantum approach to simulate self-heating effects in transistors based on silicon nanowires and estimate the resulting performance degradation. Our self-consistent thermoelectric simulations are based on the nonequilibrium Green's function approach and provide the heat power transferred from electrons to phonons, thus allowing the calculation of the local temperature and its impact on...
