Résumé
Abstract

Nous procédons à un bref survol des mesures et prédictions récentes concernant les propriétés thermoélectriques de molécules individuelles ou de nanorubans poreux, puis nous discutons quelques-uns des principes sous-jacents aux stratégies visant à augmenter leurs performances thermoélectriques. On relèvera parmi ces dernières (a) l'utilisation de pentes élevées du coefficient de transmission électronique $T (E)$ , (b) la création de structures avec des pics de transmission et (c) l'exploitation de ces derniers. Pour atteindre de hautes performances, nous suggérons que cette dernière approche puisse être la plus fructueuse, puisqu'elle est moins susceptible de présenter des élargissements inhomogénes. Afin d'extrapoler les propriétés thermoélectriques d'une ou de quelques molécules à des films moléculaires monocouche, nous discutons aussi la pertinence de l'utilisation d'une moyenne du coefficient Seebeck pondérée par la conductance.

We provide a brief overview of recent measurements and predictions of thermoelectric properties of single-molecules and porous nanoribbons and discuss some principles underpinning strategies for enhancing their thermoelectric performance. The latter include (a) taking advantage of steep slopes in the electron transmission coefficient $T (E)$ , (b) creating structures with delta-function-like transmission coefficients and (c) utilising step-like features in $T (E)$ . To achieve high performance, we suggest that the latter may be the most fruitful, since it is less susceptible to inhomogeneous broadening. For the purpose of extrapolating thermoelectric properties of single or few molecules to monolayer molecular films, we also discuss the relevance of the conductance-weighted average Seebeck coefficient.
