Fast-LPG Sensors at Room Temperature by α-Fe₂O₃/CNT Nanocomposite Thin Films

Figure 1

The Raman spectrum of the as-grown CNT and α-Fe₂O₃/CNT nanocomposite films measured in (a) low-frequency and (b) high-frequency regions. The inset in (a) shows a comparison between Raman spectra of as-grown CNTs, α-Fe₂O₃/CNTs, and α-Fe₂O₃ reference.
