| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | We perform a series of molecular dynamics (MD) simulations to investigate the transport process of heat in a hotspot region in Bulk and SOI Fin structures, and we analyze how the heat transport process depends on the thickness of buried oxide (BOX). The result shows that the heat flow from the hotspot to Si substrate is impeded when the BOX layer exists even if the thickness is only one atomic layer. Our phonon distribution analysis suggests that the heat transport in the SOI Fin structure is impeded since acoustic phonons stay in the Fin region. This study indicates that having a heat duct in a device can be effective to avoid the self-heating problem. | |
