CVD growth of large-scale and highly crystalline 2D chromium telluride nanoflakes

Abstract

Recently, 2D magnetic materials have attracted much attention due to their potential applications in spintronic devices. Chromium telluride (CrTe) flakes have been reported for hard magnetism with a strong perpendicular anisotropy. However, the synthesis of large-scale CrTe nanoflakes on SiO2/Si substrate is still a challenge. Here, we report the synthesis of large-scale CrTe nanoflakes with a size of up to ∼250 μm on a SiO2/Si substrate via chemical vapor deposition (CVD). Our work demonstrated an effective pathway to synthesize large-scale 2D transition metal tellurides.
