Recent 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 ...
متن کاملTip-Enhanced Raman Spectroscopy with Picosecond Pulses.
Tip-enhanced Raman spectroscopy (TERS) can probe chemistry occurring at surfaces with both nanometer spectroscopic and submolecular spatial resolution. Combining ultrafast spectroscopy with TERS allows for picosecond and, in principle, femtosecond temporal resolution. Here we couple an optical parametric oscillator (OPO) with a scanning tunneling microscopy (STM)-TERS microscope to excite the t...
متن کاملTip-enhanced Raman spectroscopy of graphene-like and graphitic platelets on ultraflat gold nanoplates.
In this study, tip-enhanced Raman spectroscopy (TERS) is used to characterize graphene-like and graphitic platelets composed of a few layers of graphene. Specifically, gap-mode TERS geometry provides a larger enhancement of the local electromagnetic field at the junction formed by a gold sharp tip and a gold substrate. Graphene-like platelets are deposited onto ultra-flat thin gold nanoplates u...
