Micro-Raman evidence for topological charge order across the superconducting dome of La_{2-x)SrxCuO4

D. Lampakis, E. Liarokapis, C. Panagopoulos

The doping dependence of the micro-Raman spectra of high quality La_{2-x}Sr_xCuO_4 microcrystals with x=0.0-0.45 has been investigated in the region 10-300 K. The phonon at ~100 cm…
