Molecular electronics

Molecular electronics is the use of molecules as the primary building block for electronic circuitry. A molecular approach, it is hoped, will enable the construction of much smaller circuits than is currently possible using the more conventional semiconductors such as silicon. The motion of the electrons in such devices is inherently governed by quantum mechanics.

    To demonstrate charge transfer in different Marcus regimes in an organic semiconductor, precise tuning of the material’s electronic properties is required. Here, the authors use a three-terminal hot-electron technique to access the Marcus regimes for electronic transport in organic thin films.

    All-carbon electronics holds promise beyond the conventional silicon-based electronics, but it remains challenging to manufacture them with well-defined structures thus tunability. Tan et al. control charge transport in single-molecule junctions using different fullerenes between graphene electrodes.

    It remains a challenge to fully control molecular electronics. Here, Meng et al. show a reversible two-mode single-molecule switch, where the conductance through the molecular backbone is controlled by an in situ chemical gating via bias-dependent transcis isomerisation on an azobenzene sidegroup.

    The electronic structure and transport properties of organic semiconductors are known not to follow standard semiconductor models and a complete understanding is still lacking in the literature. The authors experimentally and theoretically demonstrate the role of phonon–charge interactions on the highest occupied molecular orbital and mobility of the organic semiconductor tetracene.

    Measurements with a lateral spin pumping device architecture suggest that long spin diffusion lengths of more than 1 μm are possible in conjugated polymer systems that have a sufficiently high spin density.

    In this Review, the principles developed for fabricating reliable molecular junctions and tuning their intrinsic properties are examined from the point of view of the electrode, the interface and molecular engineering. The various functionalities demonstrated in molecular junctions through molecular design are discussed, along with the open challenges in the field.
