Figure 3From: Room temperature-synthesized vertically aligned InSb nanowires: electrical transport and field emission characteristicsXPS spectra of the synthesized nanowires. (a) The In 3d core-level spectrum. (b) The Sb 3d core-level spectrum. (c) FTIR spectrum of the synthesized InSb nanowires. The inset shows (αhν)2 versus hν curve for InSb nanowires. (d) Schematic diagram of the InSb energy bandgap.Back to article page
