THE STUDY OF THE GROWTH MECHANISMS OF ALLOY FILAMENTARY CRYSTALS (WHISKERS) GROWN FROM SOLIDS.

Abstract

In an attempt to discover the mechanism by which the transport of atoms occurs under extreme microscopic stress gradients, alloy filamentary crystals were grown from the solid plating subjected to lateral compression. Enrichment of one species in the filamentary crystal would be expected if diffusion were the controlling mechanism. X-ray lattice diffraction measurement of the atomic spacing of Pb-In and Sn-In alloys appears promising. Also electron microprobe appears promising if shape and size effects can be calibrated. Absolute composition measurements are still inconclusive but the variation of composition along several filamentary crystals was less than 1%. (Author)
