Two‐Dimensional Molybdenum Telluride (MoTe ₂ ): Synthetic Strategies, Physical Properties, and Future Perspectives

ABSTRACT Molybdenum ditelluride (MoTe ₂ ) has attracted extensive attention in the development of ultra‐compact electronic and optoelectronic devices due to its compelling two‐dimensional (2D) layered structure and unique physical properties that are absent in its bulk counterparts. This article reviews the properties, synthesis methods, and applications of MoTe ₂ . The review briefly outlines the structure of MoTe ₂ and its typical characteristics, including phase transitions, optoelectronic properties, structural stability, ferromagnetism, and moiré properties. Various preparation methods for 2D MoTe ₂ , such as exfoliation, phase engineering, deposition techniques, hydrothermal synthesis, and molecular beam epitaxy, are described in detail. Subsequently, the applications of MoTe ₂ in fields including catalysis, field‐effect transistors, artificial synaptic devices, optoelectronic devices, and spintronic devices are introduced. Finally, perspectives on future research directions and accompanying challenges are presented. Achieving high‐quality, wafer‐scale 2D growth of MoTe ₂ is expected to make this material an ideal candidate for phase engineering and novel near‐infrared photonics and optoelectronics.
