Metal-Insulator Phase Transition in Quasi-One-Dimensional VO₂ Structures

Figure 6

(a) Temperature dependence of XRD data measured upon heating from VO₂ nanobeams epitaxially grown on a c-cut sapphire. (b) Temperature-dependent Raman spectra obtained from a bent VO₂ nanobeam on a c-cut sapphire substrate (left panel). Temperature dependence of XRD data from ensembles of the VO₂ nanobeams, measured during a cooling cycle from 303 to 6 K (right panel). Panels (a) and (b) adapted with permission from [34] and [35], respectively.
