Hole Localization in Underdoped Superconducting Cuprates Near 1/8th Doping

J. L. Cohn, C. P. Popoviciu, Q. M. Lin +1

Measurements of thermal conductivity versus temperature over a broad range of doping in YBa${}_2$Cu${}_3$O${}_{6+x}$ and HgBa${}_2$Ca${}_{n-1}$Cu${}_n$O${}_{2n+2+\delta }$ ($n$=1,2,3) suggest that sma…
