SEM micrographs of the superconducting devices based on Bi2Se3 single crystals corresponding to samples B (a) and C (b) previously discussed. The W-C deposit in sample B is indicated by the green shaded region, whereas in sample C, the deposit covers the entire width. Insets show a magnified view of the corresponding holes with the precise determination of their dimensions.
