Correlation between $T_{\mathrm{c}}$ and the Pseudogap Observed in the Optical Spectra of High $T_{\mathrm{c}}$ Superconducting Cuprates

Setsuko Tajima, Yuhta Itoh, Katsuya Mizutamari +6

We studied the temperature dependences of the optical spectra for optimally and underdoped Bi${}_2$Sr${}_2$Ca${}_2$Cu${}_3$O${}_{10+z}$ single crystals. Similarly to the other cuprates' case…
