抄録

In-plane and out-of-plane thermopowers have been measured for lightly-doped (insulating) and optimally-doped (superconducting) Bi₂Sr _2-xLa_xCaCu₂O_8+δ single crystals. The anisotropy of the thermopower S_c/S_ab is very large in the superconducting samples, while it is close to unity in the insulating ones. The thermopower of the insulating samples increases in proportion to T, suggesting that the localized carriers around at (π/2,π/2) cause the variable range hopping transport.
