Materials and Properties

Bi:2212; [Bi-Sr-Ca-Cu-O]
Material Specification for Bi:2212; [Bi-Sr-Ca-Cu-O] Process: Solid State Reaction
Notes: "Single crystals... were grown by the following method: 150g of the stoichiometric mixture of Bi2O3, CaCO3, SrCO3 and CuO powders were pre-calcined and heated in alumina crucible to 1010 °C, held for 16 hours at this temperature and slowly cooled down (4 °C/h) to 750 °C. The crystals were mechanically separated by breaking the crucible."

Measurement Method: Thermopower measurement
"... for the in-plane thermopower, S , the sample size was 4x0.2x0.005 mm3 and 1x1x0.1 mm3 for the out-of-plane thermopower, Sc. The sample for S was spanned between two miniature heaters. Gold wires of 12µm diameter were used as electrodes and Chromel-constantan differential thermocouples were glued on the sample for measuring the temperature gradient. For Sc gold stripes were glued onto the whole ab surfaces, attached to the heaters serving also as electrodes. The thermoelectric voltage was generated by creating typically a temperature gradient of 1K by alternately energizing the heaters."
