要旨

This article gives a topical review of the application of the scanning tunnelling microscope (STM) to the characterisation of thin films (typically monolayers) of organic molecules on surfaces. Three classes of molecules are considered: “self-assembled” thiol monolayers, macrocycles, e.g. porphyrins and cyclophanes, and passivated nanoparticles. Typically these molecules are deposited onto the surface of, e.g. gold/graphite, from a solution. The STM is shown to be a tool not just for imaging, from the morphology of the film down to the level of individual molecules, but also for molecular manipulation and for electrical measurements. Indeed, an appropriate understanding of the electrical characteristics of the STM measurement is essential for successful imaging of organic (or biological) molecules.

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
