Abstract
Crystalline atomic/molecular layer deposited ZnO:organic superlattices form a fundamentally new exciting family of coherent multilayered thermoelectric materials. They retain the n-type electrical transport properties derived from the parent ZnO lattice, while the organic molecular layers reduce the thermal conductivity. The controlled nanostructuring opens up the possibility of improving the thermoelectric characteristics of the parent oxide. Here we employ quantum chemical methods to rationalize our experimental results on the ZnO:organic superlattices and determine the thermoelectric structure-property relationships arising from the nanoscale layer-by-layer engineering of ZnO. Our results reveal the importance of systematic tailoring of the organic superlattice component and provide us with atomic-level guidelines for the rational design of novel hybrid inorganic-organic thermoelectrics.Description
