Fig. 1From: Nanostructured Bi2Te3 Prepared by a Straightforward Arc-Melting Method a XRD pattern for as-grown Bi2Te3, Rietveld-refined in the space group R-3m. A strong preferred orientation is observed, enhancing the [0 0 l] reflections, marked with an arrow. b Observed (crosses), calculated (full line), and difference (at the bottom) NPD profiles for Bi2Te3 at RTBack to article page
