Van der Waals 2D Transition Metal Tellurides

As important members of transition metal chalcogenides (TMCs), transition metal tellurides (TMTs) have drawn much attention for their various crystal structures with various physical properties. These various structures and structural transitions between them not only are fascinating in the fundamental studies, but also provide unprecedented opportunities in novel device design and applications. In this review, the recent developments in the area of TMTs are outlined. First, the unique crystal and electronic structures of TMTs are introduced. Then the TMTs preparation strategies, including novel exfoliation technique and chemical vapor deposition (CVD), are reviewed. Moreover, the distinctive physical properties of TMTs such as phase transition, intrinsic ferromagnetism, and superconductivity are summarized. Additionally, an overview of device applications in the electronics and optoelectronics field is provided. The prospect for the research of TMTs is presented at the end.
