Heterostructures composed of two-dimensional (2D) and three-dimensional (3D) materials have opened novel ways of advanced device manufacturing and research of emergenet phenomena. Advanced epitaxy techniques, such as van der Waals and remote epitaxy, enable to prepare high-quality architecture consisting of incommensurate materials. Nevertheless, remote epitaxy on non-graphene (2D) materials has rarely been studied even though it has a broad and immediate impact on various disciplines in basic science and applied research.<br/>Here, we present remote epitaxy of ZnO on monolayer MoS<sub>2</sub> and the realization of a whispering gallery-mode (WGM) cavity composed of a single crystalline ZnO nanorod and monolayer MoS<sub>2</sub>. Cross-sectional transmission electron microscopy and first-principles calculations revealed that the non-graphene 2D material interacted with overgrown and substrate layers, and also exhibited lattice transparency. The WGM cavity embedding monolayer MoS<sub>2</sub> showed enhanced luminescence of MoS2 and multimodal emission. We will also discuss interfacial phenomena in 2D/3D heterostructures prepared by remote epitaxy.
