Abstract:Figure of merit is an essential quantity to describe the efficiency of a thermoelectric device and asymmetry in transmission probability is the main requirement to increase the efficiency. Keeping this fact in the mind, here we choose a Sierpinski Gasket (SPG) triangle, a nice example of fractal lattice, as the functional element since it has peculiar energy spectrum compared to the traditional elements. In the framework of tight binding (TB) model we calculate all the thermoelectric quantities using Landauer’… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
