Resonant Raman scattering in mercurate single crystals
We report resonant electronic Raman scattering in optimally doped single layer HgBa2CuO4+δ (Hg-1201) and trilayer HgBa2Ca2Cu3O8+δ (Hg-1223) single crystals. Analysis of the B1g and B2g channels in the superconducting state of Hg-1201 advocates for a gap having d-wave symmetry. In addition a resonant study B1g pair-breaking peak and the A1g peak suggests that the A1g peak is not directly related...
متن کاملSpin-orbit splitting in single-layer MoS2 revealed by triply resonant Raman scattering.
Although new spintronic devices based on the giant spin-orbit splitting of single-layer MoS(2) have been proposed, such splitting has not been studied effectively in experiments. This Letter reports the valence band spin-orbit splitting in single-layer MoS(2) for the first time, probed by the triply resonant Raman scattering process. We found that upon 325 nm laser irradiation, the second order...
متن کاملResonant Raman scattering in O2
Raman scattering of molecular oxygen in the region of the Schumann–Runge absorption band system is calculated from first principles in the second order of perturbation theory in the interaction of photon–electron operator. Quantitative predictions are given for the cross sections for scattering of photons and a detailed comparison is made with available measurements. The behavior of Raman spect...
متن کاملResonant Raman scattering in antiferromagnets
Two-magnon Raman scattering provides important information about electronic correlations in the insulating parent compounds of high-Tc materials. Recent experiments have shown a strong dependence of the Raman signal in B1g geometry on the frequency of the incoming photon. We present an analytical and numerical study of the Raman intensity in the resonant regime. It has been previously argued by...
متن کاملResonant Raman scattering of the smallest single-walled carbon nanotubes.
We report optical properties of the smallest single-walled carbon nanotubes (SWNTs) with a diameter of only 3 A. These ultrasmall SWNTs are fabricated in the elliptical nanochannels of an AlPO-11 (AEL) single crystal. Polarized and resonant Raman scattering unambiguously revealed that these 0.3 nm SWNTs are of (2,2) armchair symmetry. Interestingly, the (2,2) armchair tube has two metastable gr...
