✦ Synopsis

The superconducting BiSrCaCuO whiskers were grown from a melt-quenched phase at a temperature near the melt point. Temperature dependencies of the growth rate at different compositions of the initial melt-quenched phase have been determined. Addition of 5 at.% Pb provides a new growth region at lower temperatures. Tunnel contacts formed by annealing of silver paste show quasi-periodic peaks on the dV/dI(V) dependence, that can be explained by quantum size effect. Photolithography technique is supposed to form reproducible small-arrea contacts to whisker.
