초록

Semiconductor nanostructures or thin films are vital components of modern optoelectronic devices, such as light-emitting diodes, sensors, or transistors. While single crystalline wafers are used as heteroepitaxial templates for them, increasing demands on flexibility or transferability require separation of the grown semiconductor structures on such substrates, which is technically challenging and expensive. Recent research suggests that large-scale 2D nanomaterials can serve as heteroepitaxial templates and provide additional functionalities such as transferability to foreign substrates or mechanical flexibility. In this paper, growth, structural properties, and optoelectronic device applications of semiconductor nanostructures or thin films which are heteroepitaxially grown on large-scale 2D nanomaterials are reviewed.
