要旨

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.

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
