Abstract:Alumina is historically a difficult material to characterize as a result of both its amorphous nature and the large range of densities and local atomic coordination topologies present. Alumina is ubiquitously employed as a high-dielectric-constant material in electronic devices, thus understanding the microscopic physics governing its structural and heat-transport properties is of key relevance for e.g. the design of heat management in these devices. Here we rely on first-principles techniques to characterize … Show more
