Raman Scattering from Charge Density Waves and Superconducting Gap Excitations in 2H-TaSe2 and 2H-NbSe2Many transition-metal dichalcogenides undergo phase transitions of the charge-density-wave (CDW) type. 1 The metal atoms are found at the center of hexagonal layers where they bind covalently and...

The linear chain model of Wieting is used here to predict the frequency of the E1g Raman active mode in the layer compound 2H-niobium selenide. A careful Raman study near this predicted frequency has shown a weak band whose polarisation suggests that it is the E1g mode.DOI...
In contrast, the semiconducting MX2 materials present an excitonic resonance at the direct gap, and consequently, the double-resonance Raman bands of MX2 are not dispersive, and only their intensities depend on the laser energy. In this... MA Pimenta,ED Corro,BR Carvalho,... - 《Accounts of...
Raman scatteringCDWMagnetotransport2H-NbSe2 is known to be an archetype layered transitional metal dichalcogenide superconductor with a superconducting transition temperature of 7.3 K. In this article, we investigate the influence of Sn intercalation on superconducting properties of 2H-NbSe2. Sn being ...
In the Raman spectroscopy measurements, the appearance of CDW amplitude mode is accompanied by the freezing of the two-phonon mode. The frequency of CDW amplitude mode under pressure follows modified mean-field theory with power-law scaling (& beta; = 0.18). The renormalization of the Raman ...

RAMANThe longitudinal low frequency acoustic and optic phonon modes of 2H-NbSe2 have been determined for the Gamma - M direction with inelastic neutron scattering at 50 K close to the charge density wave transition temperature. We found a softening of the two low frequency modes which are ...
