摘要：
Thermoelectric properties of multi-layered system is investigated theoretically. It is shown that the figure of merit can be improved by eliminating the contributions from low energy carriers to transport processes. Thus the barrier layers which enhance the low energy scattering can be used to eliminate the contributions from the low energy carriers. Appropriate thickness of the barrier layer is estimated by using transmission probability for a single potential barrier. Scattering probability due to multiple potential barriers are derived intuitively and transport coefficients are calculated based on this scattering probability.
