Stokes bands, respectively. Here,ωνis the frequency of a (Raman active) vibrational mode of the crystal, i.e. a phonon. Depending on the symmetry of the phonon modes and polarization of the electromagnetic fields, a phonon mode may be active or inactive in the Raman spectrum. Fig. 1:S...
The various 2DMs with wide spectrum can be insulator, topological insulator, semiconductor, semi-metal, conductor, or superconductor. Their Raman spectra are discrepant in position, width, and intensity of Raman peaks. Here, we take hexagonal boron nitride (hBN, insulator), Bi2Se3 (topological ...
The power of the 785 nm laser was set to 105 mW. The data acquisition time of SERS measurements was set to 3s for each spectrum, and the wavenumber range was set to 200–2000 cm−1. 2.4. SERS detection of CV, 4-MPY, and microplastics Both CV and 4-MPY are probe molecules for ...
(Adar, 1978). When haem proteins are excited with a laser wavelength coincident with these electronic transitions, only the Raman spectrum of the haem moiety is enhanced (RR effect). In particular, excitation in the Soret and Q bands leads to the intensification of the haem vibrational modes...
However, in NIMMs there exist inhomogeneities due to the roughness of sample and the fluctuations in the meta-atom size of the meta-atom array, which may result in an inhomogeneous broadening for the absorption spectrum of the signal field. Related calculation including such inhomogeneous broadening...

The measurement time per pixel is therefore in practice limited to less than 1 s, which is a very short measurement time to detect few, small particles or to acquire a high-quality spectrum of the fingerprint region where many Raman bands assigned to DNA, proteins, lipids and carbohydrates ...
