Normal state thermopower of the high temperature superconductor YBa 2Cu 3O 6.5+λ
Abstract
The behaviour of the thermopower between 50 and 350 K has been determined for YBa 2Cu 3O 6.5+λ. A zero value of the thermopower below 90.6 K and a flat maximum of 5.52 μV K -1 at about 100 K have been found. The thermopower shows metal like behaviour. Carrier concentration 2.4 × 10 21cm-3 and carrier mobility 2.5 cm 2 V -1 s -1 at ambient temperature were determined.
