Figure 2: SHINERS of SAM-modified surfaces.
From: Exploitation of desilylation chemistry in tailor-made functionalization on diverse surfaces
(a) Schematics of SHINERS configuration. (b) STM image showing the surface morphology of 2-modified Au(111) surface. Imaging conditions: bias=300 mV, tunnelling current=100 pA. Inset: STM image shows the atomic resolution of Au(111) (1 × 1) atoms underneath the 2 SAM with extreme imaging conditions of low bias voltage (10 mV) and high setpoint of tunnelling current (3 nA). (c) Cross-section profile along the white line in b showing the apparent height of the monolayer. (d) Raman spectra of 2 in the solid state (d-1) and as a monolayer of 2 on Au(111) (d-2), Pt(111) (d-3), Pd(111) (d-4) and HOPG (d-5) surfaces. (e1–4) Magnifications of the interesting regions as indicated in d. (f) Raman spectra of 1 (f-1), 2 (f-2) and 3 (f-3) on Au(111) within the specified frequency regions of the C≡C stretching mode.
