| Abstract Scope |
As the world moves into an energy efficient future, the need for effective thermoelectric material becomes more evident. To understand the phenomenon of thermoelectric material extensive study of electrical as well as thermal transport is required. The method for projecting electrical conduction in material has been developed, now we aim to apply same to the thermal transport in the material. The problem of the spatial projected thermal conductivity is approached using two methods, one is by performing long molecular dynamics simulations, and another is using the phonon approach based on the previous work by Allen and Feldman. Using these methods, we study the conduction in models of carbon and silicon materials including the grain boundaries. |
