摘要：

Measurements of thermal conductivity versus temperature over a broad range of doping in YBa2Cu3O6+x and HgBa2Can-1 Cu(n)O2(n+2+delta) (n = 1,2,3) suggest that small domains of localized holes develop for hole concentrations near p = 1/8. The data imply a mechanism for localization that is intrinsic to the CuO2 planes and is enhanced via pinning associated with oxygen-vacancy clusters. [S0163-1829(99)01805-6].
