Crystal Growth of Bi${}_2$Sr${}_2$CaCu${}_2$O${}_{8+\delta }$ Whiskers from Pulverized Amorphous Precursors

Abstract

High-transition temperature superconducting whiskers of Bi${}_2$Sr${}_2$CaCu${}_2$O${}_{8+\delta }$ were successfully grown from pulverized amorphous precursors. The obtained whiskers revealed a typical composition and diffraction patterns of a superconducting Bi-2212 phase. The whiskers from tiny precursors exhibit a spiral feature, suggesting a contribution from the growth mechanism of both vapor-liquid-solid and compressive stress models. The proposed method provides longer whiskers against the growth period, compared with that from conventional root-growth method.
