Optical spectroscopy and ultrafast pump-probe study on Bi${}_2$Rh${}_3$Se${}_2$: evidence for charge-density-wave order formation

T. Lin, L. Y. Shi, Z. X. Wang +6

The parkerite-type ternary chalcogenide Bi${}_2$Rh${}_3$Se${}_2$ was discovered to be a charge density wave (CDW) superconductor. However, there was a debate on whether the observed phas…
