A one-step chemical vapor deposition approach for solid solution PrxNd1−xB6 nanowire growth

Abstract

Dual-rare earth hexaborides Pr_xNd_1−xB₆ nanowires have been successfully synthesized on silicon substrates by a one-step CVD method at a temperature of 1030 °C. The quasi-aligned nanowires are shown to be structurally uniform and well-doped single crystals based on comprehensive analysis. The present preparation technique is an effective and invaluable method to develop and optimize dual-REB₆ nanostructured emitters.
