Raman scattering of two‐dimensional MoO <sub>2</sub> flakes at high pressure
摘要 二维（2D）MoO 2 是一种非层状二元材料，因其在催化和电子学中的潜在应用而被广泛研究。然而，2D MoO 2 的制备仍然具有挑战性。在此，通过化学气相沉积（CVD）方法，我们报道了在蓝宝石基底上生长2D菱形MoO 2 薄片。原子力显微镜显示CVD生长的MoO2具有较薄的厚度。能量色散X射线光谱验证了CVD‐MoO 2 化学计量比为1:2。扫描透射电子显微镜表征显示，CVD获得的2D MoO 2 薄片具有高质量的单晶特性。通过温度依赖性和高压拉曼光谱，我们分别研究了2D MoO 2 的声子振动和结构转变。这项研究为探索2D MoO 2 的压力依赖性特性铺平了道路。
