Summary

Abstract

Van der Waals (vdW) heterostructures is a rapidly emerging field that promises to produce on-demand properties for novel optoelectronic devices. Assembly of dissimilar two-dimensional atomic crystals in the vdW heterostructure enables unique features and properties which are fundamentally different from individual 2-dimensional (2D) crystals. Currently, most growth and fabrication methods prohibit large scale, micron-thick and robust heterostructures. An alternative approach is the one based on liquid phase exfoliation allowing the possibility of scalable thin films and composites. Such thin films have inherent and predicted advantages: they can display new beha...
