Fig. 2: Crystal structure analysis of BSCNTx ceramics.

a X-ray diffraction patterns of the ceramics with increasing x and (b) enlarge view of selected diffraction peak. c Projection of BSCNT0 and BSCNT0.30 unit taken along [001] (P4bm, solid line). d Raman spectroscopy of BSCNTx ceramics. e The variation in wavenumber v2 and v5 Raman vibration modes were divided by Gaussian-Lorentzian function.
