“…Similar effects were reported for C 60 molecules and an electrochemically etched Au tip with an apex 20 nm in diameter (this tip is mounted in a shearforce set-up). 1 In addition, the authors also noted that this approach has a spatial resolution of about 55 nm.…”

“…Stöckle et al 1 reported a significant enhancement of the Raman signal if a metalized AFM tip is brought within a few nanometers of a dye film deposited on a glass substrate. They reported a more than 30-fold net increase in the Raman signal by the tip.…”

“…[1] The tip apex functions as a single 'hot' spot, which enhances the Raman scattering from the scanned sample area. At optimized conditions, single-molecule sensitivity [2] can be achieved and the spatial resolution can reach ∼10 nm, [3] making TERS an important candidate for nanoscale chemical analysis.…”

“…Since the first reports in 2000, [1,4,5] TERS has been successfully implemented in different disciplines, such as life science, [6,7] material science, [8] surface science, [9] etc. Besides these applications, TERS has also been used to study some of the most fundamental aspects of its cousin technique, surface-enhanced Raman spectroscopy (SERS), especially the properties of the 'hot' spot in SERS, since TERS is playing with a single 'hot' spot and can collect both the topographic information and the Raman spectrum simultaneously.…”

“…[8][9][10][11][12] Here, a noble metal SPM tip is irradiated by focused laser light, leading to the excitation of localized surface plasmons resonances (LSPRs) and the introduction of the lightning rod effect, as schematically shown in Fig. 1(a) (we name this as "direct excitation").…”
