Special Issue Information

Dear Colleagues,

This Special Issue, “Advances in Molecular Electronics: Materials and Devices”, will address the most recent progress in the field of molecular electronics, ranging from molecular design and synthesis to device integration strategies and functioning. Molecular electronics is a multidisciplinary branch of science that aims to exploit the intrinsic properties of organic and inorganic molecules and the versatility of synthetic chemistry for conceived electronic devices with reduced sizes. Great progress has been achieved in addressing fundamental questions in the field, such as molecular structure–conductance relationships and the role and reproducibility of the electrode (E)–molecule (M) contacts and the EM bonding motifs, and desired functions such as diodes, capacitors, and transistors have been demonstrated at the molecular level. Despite this impressive advancement, we still have challenges ahead in the effort to achieve robust functional solid-state molecular devices. To contribute to addressing these open challenges, original papers are solicited to cover all aspects involved in the design and preparation of advanced functional molecular-based devices from a fundamental point of view (experimentally and theoretically) to an applied one. In particular, it is of great interest to cover the recent developments in synthesis of functional molecular components; single and large molecular junctions (fabrication, characterization, charge-transport mechanism rationalization); molecular function integrity (charge, spin, conformation, etc.) upon electrode binding; molecule–electrode interface characterization; molecule integration into devices (i.e., to tune electrode work function or to implement additional functions); and self-assembled monolayers applied to sensing, memory, switching, and actuation functions.

The field of molecular electronics is prompted by tremendous opportunities for using a single-molecule and molecular monolayers as active components in integrated circuits. Until now, a wide range of molecular devices exhibiting characteristic functions, such as diodes, transistors, switches, and memory, have been demonstrated. However, a full understanding of the crucial factors that affect charge transport through molecular electronic junctions should yet be accomplished. Remarkably, recent advances in transition voltage spectroscopy (TVS) elucidate that it can provide key quantities for probing the transport characteristics of the junctions, including, for example, the position of the frontier molecular orbital energy relative to the electrode Fermi level and the strength of the molecule–electrode interactions. These parameters are known to be highly associated with charge transport behaviors in molecular systems and can then be used in the design of molecule-based devices with rationally tuned electronic properties. This article highlights the fundamental principle of TVS and then demonstrates its major applications to study the charge transport properties of molecular electronic junctions. Full article
