Advances in Two Dimensional Layered Transitional Metal Dichalcogenides (TMDCs) Coupled with Plasmonic Nanostructures

About this Research Topic

Electromagnetic waves can be scattered or absorbed by few-layer thick/atomically thin two dimensional materials with semiconducting structures. This phenomenon can be enhanced by the surface plasmon resonance (SP) structure of different noble metal nanostructures such as gold (Au) and silver (Ag). Recently, significant theoretical, numerical, and experimental studies have been conducted investigating the light-matter interaction occurring in these complex structures. Particular materials of interest are composed of atomically thin Transition metal Dichalcogenide (TMDC) materials (i.e. MoS2 and WSe2) functionalized with periodic and/or randomly distributed metal nanostructures. For example, surface-enhanced Raman scattering (SERS) has been utilized within sensing applications due to the incorporation of Au nanoparticles on top of TMDCs surface. In addition to this, the modulation of luminescence and absorption in 2D TMDC materials has been extensively studied when functionalizing with metal nanostructures or quantum dots (QDs). QDs with strong size tuneable absorption, carrier multiplication, and long exciton lifetime could be a potential surface inducer on 2D material for optoelectronic device applications. Overall, modulation of the optical properties of 2D materials is very important in order to further enhance the optical response in practical electronic device applications in the field of optoelectronics, photonics, and nanoplasmonics.

Currently, 2D materials are one of the fastest-growing research fields despite having many challenges and poor performance in device integration. Current research looks to analyze the coupling strength of light excited plasmons with the excitons of TMDC semiconductors to further enhance the sensing performance, charge transfer process, and exciton-exciton interaction in QDs-2D materials. The optimization study of modulating the optical properties i.e. absorption, the luminescence of 2D materials via controlled variation of the structural parameters of the plasmonic array or QDs incorporation are also of keen interest. In energy converters, sensors, and photodetector like optoelectronic devices, the device efficiency modulation when 2D surface hybridized with nanoplasmonic or QDs structure to observe an enhancement in performance due to photo-induced effect are also of interest to researchers.

This Research Topic will cover a broad range of the latest development, synthesis, applications, and exciting results of 2D layered TMDCs material coupled with plasmonic nanostructures in the area of nanoplasmonic optoelectronics. The aim is to bring the latest methods to enhance light-matter interaction in thin 2D semiconductors via modulating absorption, scattering, and luminescence for future industrial applications. This will cover both fundamental and applied research in energy conversion, tunable optical detectors, quantum light source, sensor, SERS sensor, etc. Original Research and Reviews/Mini-reviews are welcomed on, but not restricted to, the following topics:

• Study of plasmon coupling strength with exciton in atomically thin TMDCs semiconductor
• Theory and simulation study of plasmonic metal decorated TMDCs materials
• Methods of tuning and novel fabrication techniques for patterning plasmonic structure on TMDC material surface
• Nanotechnology-based surface modification and functionalization of TMDC Materials
• Synthesis method of composite hybrid materials of noble metal and TMDCs materials
• Synthesis of colloidal quantum dots – 2D material TMDC hybrid heterostructure
