Tungsten ditelluride (WTe₂) is one of the low symmetry two-dimensional materials and exhibits extremely large magnetoresistance (XMR) below 10K. Understanding of novel properties in the materials is highlighted to induce unique properties at elevated temperature. Study of the temperature dependent MR is essential for real applications and deep insights. Most reported studies on fundamental issues are mainly achieved in exfoliated WTe₂ (for reduced disorders) which is encapsulated with h-BN layers (for ideal interfaces). Here, we demonstrate synthesis and enhanced performances of the synthesized WTe₂ single crystals. Tunable thickness and high crystallinity of the WTe₂ are achieved using promoter-assisted CVD. A large MR of the CVD-grown WTe₂ is experimentally realized.
