Outline of Final Research Achievements

In this research, structural optimization methods for nano-structure of thermoelectric material were developed in order to generate high-performance devices. Since the characteristics of thermoelectric material are determined by behavior of phonon and electron, we, first, developed numerical analysis methods based on Boltzman transportation equation. Next, we investigate the methodology to calculate the shape derivatives based on the adjoint method. Finally, we developed structural optimization method for the nano-structure of the themoelectric materials.
