Surface enhanced Raman scattering of a single molecular junction
文献信息

The characterization of a single molecular junction is essential to investigate and utilize the single molecular junction in single molecular devices. Vibration spectroscopy is a promising technique for characterizing the atomic structure of the single molecular junction. In this review paper, we describe the surface-enhanced Raman scattering (SERS) as a vibration spectroscopy of a single molecular junction. A strong electric field is formed in the nanogaps in the single molecular junction, which enhances the intensity of the Raman signal. The Raman signal from a single molecule in the nanogap is selectively observed thanks to the strong electric field. Simultaneous SERS and conductance measurements provide information of the geometric structure of the single molecular junction, which can clarify the single molecular dynamics.

Physical Chemistry Chemical Physics

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.
