WebJul 19, 2024 · Here, we report fast, non-destructive and full phase change of Al2O3-encapsulated 2H-MoTe2 thin films to 1T'-MoTe2 using rapid thermal annealing at 900 °C. Phase change was confirmed using Raman spectroscopy after very short annealing duration of 10 s both in vacuum and nitrogen ambient. No thickness dependence of the transition … Webregion is masked by the cantilever. Therefore, photo induced effect for 2H-MoTe 2 is avoided. All the electrical measure-ments, Raman spectroscopy and SGM observation were performed at ambient condition. 3. Results and discussion 3.1.
