Abstract
The field of nanoscale thermoelectrics began with a clear motivation for better performances of waste heat recovery processes by lowering the system dimensionality. Although this original inspiration still drives many recent developments, the field has also evolved to address fundamental questions on charge and energy transport across quantum conductors in the presence of both voltage and temperature differences. This ‘focus on’ collection provides new perspectives in the field and reports on the latest developments, both theoretically and experimentally.
Highlights
Editorial fundamental questions regarding charge and heat transport in nanoscale systems that lead to new, exciting physics, and that are the topic of this focus issue
Fiedler and Kratzer [2] show that the figure of merit ZT gets larger in quantum dot superlattices
The field offers a large wealth of opportunities in fundamental condensed matter physics
Summary
Editorial fundamental questions regarding charge and heat transport in nanoscale systems that lead to new, exciting physics, and that are the topic of this focus issue. Quasi-one dimensional systems are good candidates to observe rising thermoelectric energy conversions, as indicated by Wang et al [4] for spatially structured nanowires. Mazza et al [7] find improved efficiencies at maximum power in three-terminal quantum thermal engines.
