The resonant tunneling model is the simplest model for describing electronictransport through nanoscale objects like individual molecules. A completeunderstanding includes not only charge transport but also thermal transport andtheir intricate interplay. Key linear response observables are the electricalconductance G and the Seebeck coefficient S. Here we present experiments onunspecified resonant tunnel junctions and molecular junctions that uncovercorrelations between $G$ and $S$, in particular rigid boundaries for $S(G)$. Wefind that these correlations can be consistently understood by the single-levelresonant tunneling model, with excellent match to experiments. In thisframework, measuring $I(V)$ and $S$ for a given junction provides access to thefull thermoelectric characterization of the electronic system. A remarkableresult is that without targeted chemical design, molecular junctions can exposethermoelectric conversion efficiencies which are close to the Carnot limit.This insight allows to provide design rules for optimized thermoelectricefficiency.
