Recent Developments in Black Phosphorous Transistors: A Review

Two-dimensional (2D) materials like graphene, phosphorene, germanene, silicene, and transition metal dichalcogenides have attracted intense research attention because of their rich physics and potential for integration into next-generation electronic devices. These materials offer superior electrostatic control to their bulk counterparts, which makes them fascinating for device fabrication. After graphene and MoS₂, the most intensively explored 2D material is black phosphorus (BP). During the past half-decade, BP has notably achieved excellent performance when included in transistors. This review paper aims to throw some light on BP properties and their performance in a field effect transistor device. The state-of-the-art BP transistors are reviewed, and a balanced view of both the benefits and drawbacks is provided.
