Figure 7From: Enhanced electrical properties in sub-10-nm WO3 nanoflakes prepared via a two-step sol-gel-exfoliation methodRaman spectra (perturbation region within 600 to 1,000 cm-1) for sol-gel-developed WO 3 and exfoliated Q2D WO 3 nanoflakes. Sintered at 550°C (A) and 650°C (B), respectively.Back to article page
