Gold nanocrystal arrays as a macroscopic platform for molecular junction thermoelectrics

Author affiliations

Abstract

Efficiencies of bulk thermoelectric systems have been limited because the Seebeck coefficient and electrical conductivity are typically inversely correlated in traditional materials. Decoupling of these properties has been demonstrated in molecular junctions by capitalizing on the unique electronic transport at organic–inorganic interfaces. In this work, the thermoelectric properties of gold nanocrystal arrays with varying thiol-terminated ligands are compared to molecular junction experiments. The experimental results and supporting theory demonstrate that gold nanocrystal arrays are a valuable model system for mapping the applicability of molecular junction design rules to the design of macroscale organic–inorganic hybrid thermoelectric materials.
