(This article belongs to the Special Issue Molecular Electronics)
The field of molecular electronics is currently experiencing a renaissance. Recent advances in experimental techniques on the one hand, combined with theoretical modelling on the other, have enabled the exploration of new avenues, as well as allowing for significant progress along more traditional lines. The field is very diverse and embraces many cutting-edge research areas such as quantum interference, thermoelectrics, heat transfer, spintronics, switch devising, and biomolecular electronics. Studies on these subjects are driven by a multitude of needs in modern society: the current global quest for cheap and sustainable technology, the conversion of waste thermal energy, efficient ways of storing and processing information, and the fabrication of biocompatible and implantable devices to name but a few. Last but not least, molecules have proven to be an ideal platform for the advancement of knowledge of fundamental physics. This special issue aims at showcasing some of the many facets of research in molecular electronics and surveying the latest advances in the field. It contains seven studies, including five research papers [1,2,3,4,5] and two reviews [6,7], which span different areas of the field from both a theoretical and experimental perspective.
