Material Specification for Bi:2212; [Bi-Sr-Ca-Cu-O]
Process: Crystal Growth
Notes: The authors cite J.M. Imer et al., Phys. Rev. Lett., Vol. 62, 336 (1989), and summarize the procedure as follows. "The crystals were cleaved into thin ab-plane sheets of typical dimensions 2 x 1 x 0.01 mm3. The oxygen configuration of the crystals was altered by annealing in either oxygen (samples A and B) or a vacuum (samples C and D), using the same procedure employed in (M.F. Crommie et al., Phys. Rev. B, Vol. 41, 2526 (1990) )."

Measurement Method: Steady-state method
"The thermal conductivity was measured using a steady-state comparative technique, where a constantan wire attached in series with the sample served as a calibrated heat link. Since the thermal conductivity of the constantan enters the analysis, we determined, using an independent Joule heating method, the absolute (temperature-dependent) thermal conductivity of the constantan... Average temperature gradients across the sample were 0.5 K, and error due to radiation and heat leaks through the wires was estimated to be only a few percent... The measurements were performed along the ab plane..."
