Two-dimensional materials can exhibit a range of exceptional electronic, optical, and mechanical properties. These ultrathin materials can be produced in a diverse range of compositions and synthesized through a variety of methods, from chemical vapor deposition to liquid-phase exfoliation to micromechanical cleavage. We study 2D forms of the transition metal dichalcogenides and a range of different boron-rich compounds. Many of these materials are generated using liquid-phase exfoliation, which can be scaled up to large volumes, and enables them to cast into polymer composites and interfaced with biological systems.
