The main goal of this project is to understand and optimize the process of heat transfer across solid-oxide interfaces in nanostructures.
During the last years, a huge effort has been made to integrate the functionality of many transition metal oxides in the new generation of nano-electronic devices. This, along with the continuous miniaturization, led to a growing relevance of oxide-oxide, oxide-metal, and oxide-semiconductor interfaces in the crucial process of heat-dissipation.
We plan to build artificial van der Waals interfaces using free standing membranes of different functional oxides, as well as oxide/graphene, to decouple the electrical and thermal conductance of the interfaces. We will also probe the possibility of reconfiguring the interfacial thermal resistance using reversible oxide-ion intercalation, through chemical and physical methods.
