Synthesis and assembly of two-dimensional heterostructured architectures

Stacking atomically thin two-dimensional nanosheet materials leads to unique synergy in their inherent properties due to an intimate combination and matching that is not possible via separate individual components and phases. However, traditional synthesis and assembly methods result in poor architectural control, diffuse interfaces and restricted surface chemistry, thereby limiting their prospective potentials. This brief overview provides condensed consideration of different synthesis and assembly methods for the fabrication of diverse novel heterostructures from individual nanosheets and challenges of existing methods. Finally, future perspectives regarding crafting of well-defined heterostructures with highly controllable architectures and interfacial/surface chemistry and advanced characterization methods are highlighted.
