Abstract Scope |
We briefly describe the role of defects (vacancies and a grain boundary) on electron transport in FCC Aluminum. Next, we study the structural, electronic, thermal and transport characteristics of Aluminum with graphene and graphite additives. We use the Kubo-Greenwood formula (KGF) and plane wave DFT to compute the DC conductivity as a function of temperature by performing a thermal average of the KGF over a classical trajectory. The Space-Projected Conductivity is used to visualize and quantify the effects of the impurities on transport. |
