Abstract

Nanowires have garnered considerable attention in photonics and optoelectronics due to their unique features. Owing to the large surface area and significant potential of usage as a resonator and waveguide in photonic integrated circuits (PICs), nanowires have been applied in many research areas in nanophotonics. To enhance the properties of light emitting materials, the hybrid of nanowires and 2D materials has been deployed in many papers. This paper summarises recent studies on the application of various types of nanowires in photonics and optoelectronics, as well as the combination of nanowires and 2D materials. This review article introduces nanowires that act as resonators or/and waveguides to increase the performance of 2D materials used in PICs for light enhancement and guiding. Moreover, the review lays out the hybrid of nanowires and 2D materials that have been studied in the field of optoelectronics. The hybridization of nanowires and 2D materials for photonics and optoelectronics is discussed in this review for the outlook of future studies.

Summary

Introduction

The study of the interaction of light and matter has gained popularity for several decades. 2D insulating materials protect metal nanowires from oxidation. Metal nanowires act as waveguides [14], open nanocavities [15], and control light emission properties [16]. Kim: NWs for 2D devices compatibility with complementary metal–oxide–semiconductor (CMOS) technology while yet providing advanced electrical and optical functionality [19, 20] When these nanowires are combined with 2D materials in the form of core–shell or nanowire-on-monolayer structures, a synergetic effect is anticipated. Perovskite nanowires including CsPbBr3 have high potentials for application in piezotronic [29] and piezophototronic devices [30, 31] Their optical properties could be enhanced when incorporated with transition metal dichalcogenides (TMDs) materials. This is by enabling effective charge carrier transfer through the WS2 conducting channel while suppressing dark current. Nanowires can operate as a photonic resonator and a waveguide, which aid in understanding how nanowires can enhance the functionality of photonics and electronics devices
