| Outline of Final Research Achievements |
In this research, the temperature distributions of operated nanoscale electron devices and the impacts of its temperature increase on device performances were investigated. From electrical and thermal device simulations, a low-power device design strategy for nanoscale 3D transistors was proposed by optimizing thermal characteristics. Furthermore, from experimental evaluations of thermal conductivity of silicon nanowires, it was clarified that conventional thermal evaluation methods might contain some errors in estimations of operation tempeartures in nanoscale semiconductor electron devices.
