“…In the study by Suzuki et al [40] the G band in the TERS spectra of epitaxial graphene on the C-face of 4H-SiC exhibits position-by-position changes in both lower wavenumber shifts and spectral broadening. The analysis of the changes revealed that the shifts and broadenings have a linear correlation between each other, indicating that the changes are induced by the position-dependent local stress on graphene based on a uniaxial strain model.…”

“…Suzuki et al [40] reported a TERS investigation of stress change in the local domain of epitaxial graphene on the carbon face of 4H-SiC (0001). Epitaxial graphene grown on SiC has been a matter of keen interest because of its large sheet area, minimal defects, and electrical insulation properties of SiC, which allow the application in electronic circuits without the need of substrate transfer processes [64,65].…”

“…These methods can be used to prepare homogeneous graphene with higher quality in a larger area [49]. Suzuki et al [40] reported a TERS study on stress change in the local domain of epitaxial graphene on the carbon face of 4H-SiC (0001) and Vantasin et al [41] epitaxial graphene on 4H-SiC (0001) using TERS. These studies will be introduced in some detail.…”

“…A typical interesting feature of TERS is that it allows molecularscale view of small ensembles of molecules or even single molecules. Thus, it has been proved that TERS is a unique technique for probing very small portions of complicated materials such as graphenes and carbon nanotubes [27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46].…”

Various kinds of carbon nanotube-based and graphene-based nanomaterials are considered as future materials for electronic devices due to their outstanding properties. This review paper reports tip-enhanced Raman scattering (TERS) studies of polymer nanocomposites containing carbon nanomaterials and graphenes. TERS is an emerging spectroscopic tool that combines scanning probe microscopy and Raman spectroscopy. Compared with normal Raman spectroscopy, TERS has much better spatial resolution and sensitivity. The usefulness of TERS technique in studying structure and interactions of nanomaterials is demonstrated by introducing four TERS studies.

This article reviews the mechanism of tip-enhanced Raman spectroscopy (TERS) and its importance for characterizing graphene. The theoretical foundation of TERS and experimental implementation are discussed. Conventionally, Raman scattering is treated as a spatially incoherent process where the total signal is proportional to the scattering volume. However, in the near-field regime, the scattered fields can add coherently because the TERS interaction volume is on the same length scale as the phonon correlation length. These coherence effects are significant for two-dimensional materials as will be discussed theoretically and experimentally. Therefore, TERS provides an optical method to probe phonon correlations at the nanoscale. In addition, this article will review the TERS applications for characterizing defects, edges, and nanoscale strain in graphene. Finally, the outlook and future applications are discussed.

The thickness of multifunctional oxide films directly affects the localized enhancement of the electromagnetic field and hence is a key factor for realizing novel photonic or optoelectronic devices. To this end, we theoretically exploit the principle of tip‐enhanced Raman spectroscopy on the surface of multifunctional oxide films (bismuth ferrite and barium titanate) on a gold substrate. An electromagnetic field enhancement of up to 104 in close proximity of the tip apex was obtained. The good agreement between simulation and experiment of spatial resolution of the tip supports the validity of our model. By investigation of surface plasmon polaritons that propagates at the interface between the multifunctional film and the gold substrate, we demonstrated a thickness dependent propagation length and amplitude. This study indicates a critical thickness of the films above which neither a considerable near‐field nor a tip‐mediated excitation are observed. This confirms the validity, promise, and power of tip‐enhanced Raman spectroscopy technique for the analysis of various electro‐optic materials.
