Structural Analysis of PX-phase Pb-Ti-O Single-crystal Nanowires using Micro X-ray Beam

Abstract

Pb-Ti-O single-crystal nanowires having an unknown precise crystal structure called PX-phase were analyzed using micro x-ray beam at SPring8. The nanowires were fabricated by hydrothermal synthesis method and were dispersed on the substrate. The dispersed nanowires were mapped by scanning a micro x-ray beam, which enables us to focus the x-ray beam on a single nanowire. The x-ray diffraction of the single wire indicates that the longitudinal of the nanowire is perpendicular to the (001) plane, and the lattice spacing of (100) and (010) is identical.
