Plasmonic hybrids of two-dimensional transition metal dichalcogenides and nanoscale metals: Architectures, enhanced optical properties and devices

Hybridized with plasmonic nanoscale metals, including metallic nanoparticles and nanostructures, two-dimensional transition metal dichalcogenides (TMDs) exhibit unique enhanced optical properties, promising widespread applications in optoelectronic devices, such as photodetectors, photovoltaics and light-emitting devices. In this review, the recent developments of the plasmonic hybrids composed of TMDs and nanoscale metals are comprehensively described. First, the architectures of hybrid heterostructures are classified according to the stack site of TMDs, as well as the morphology of nanoscale metals. Then, the mechanisms behind the enhanced optical properties of plasmonic hybrids are briefly introduced. Furthermore, we elaborate the unique enhanced or tailored optical properties and the enabled applications of the hybrids of TMDs and nanoscale metals based on their architectures. Lastly, the prospect for the future fabrication trend and practical applications of the plasmonic hybrids are presented.
