Extending the plasmonic lifetime of tip-enhanced Raman spectroscopy probes.
Tip-enhanced Raman spectroscopy (TERS) is an emerging technique for simultaneous mapping of chemical composition and topography of a surface at the nanoscale. However, rapid degradation of TERS probes, especially those coated with silver, is a major bottleneck to the widespread uptake of this technique and severely prohibits the success of many TERS experiments. In this work, we carry out a sys...
متن کاملOptical nanocrystallography with tip-enhanced phonon Raman spectroscopy.
Conventional phonon Raman spectroscopy is a powerful experimental technique for the study of crystalline solids that allows crystallography, phase and domain identification on length scales down to approximately 1 microm. Here we demonstrate the extension of tip-enhanced Raman spectroscopy to optical crystallography on the nanoscale by identifying intrinsic ferroelectric domains of individual B...
متن کاملRecent Advances in Tip-Enhanced Raman Spectroscopy.
Tip-enhanced Raman spectroscopy (TERS) has experienced tremendous growth in the last 5 years. Specifically, TER imaging has provided invaluable insight into the spatial distribution and properties of chemical species on a surface with spatial resolution that is otherwise unattainable by any other analytical method. Additionally, there has been further development in coupling ultrafast spectrosc...
متن کاملTip-enhanced Raman spectroscopy: principles and applications
This review provides a detailed overview of the state of the art in tip-enhanced Raman spectroscopy (TERS) and focuses on its applications at the horizon including those in materials science, chemical science and biological science. The capabilities and potential of TERS are demonstrated by summarising major achievements of TERS applications in disparate fields of scientific research. Finally, ...
متن کاملUltrahigh-Vacuum Tip-Enhanced Raman Spectroscopy.
Molecule-surface interactions and processes are at the heart of many technologies, including heterogeneous catalysis, organic photovoltaics, and nanoelectronics, yet they are rarely well understood at the molecular level. Given the inhomogeneous nature of surfaces, molecular properties often vary among individual surface sites, information that is lost in ensemble-averaged techniques. In order ...
