Deterministic and Scalable Generation of Exciton Emitters in 2D Semiconductor Nanodisks

Abstract: valley coupling with the carrier spin, [1][2][3][4] robust exciton and trion emission [5] sensitive to biochemical molecular doping, [6,7] many-body [8,9] and valley [10][11][12][13][14][15][16] physics, and great potential in optoelectronic applications for novel photodetector, [17] electroluminescence light source, [18,19] and lasers. [20] Furthermore, single-photon emitters [21][22][23][24] were found in the transition metal dichalcogenide (TMD) semiconductors, which could serve as a cornerstone for quantum… Show more

“…The combinational approach of electron beam lithography and plasma etching to form nanosize structures may be a potential solution. Recently, the emitter-like narrow emission bands in monolayer WS 2 disks prepared by such a strategy have been observed, in which the defect-related localized excitons play a key role . The following step will be the coupling of microcavity-enhanced single-photon emitters with the on-chip waveguides and other functional photonic elements in integrated photonic circuits to verify the technological feasibility, where the waveguides can be made by silicon-based materials or planar photonic crystal membranes .…”

“…Recently, the emitter-like narrow emission bands in monolayer WS 2 disks prepared by such a strategy have been observed, in which the defect-related localized excitons play a key role. 158 The following step will be the coupling of microcavity-enhanced single-photon emitters with the on-chip waveguides and other functional photonic elements in integrated photonic circuits to verify the technological feasibility, where the waveguides can be made by silicon-based materials 159 or planar photonic crystal membranes. 160 Recently, with the silicon-nitride (SiN) microring resonators, the single-photon emission from 2D materials has been efficiently coupled into the SiN waveguide, 159 in which the bandgaps of prevailing 2D semiconductors are suitable to the transmission window of the SiN, i.e., from UV to telecommunication wavelengths.…”

“…[8] The interlayer exciton formed by Coulomb interactions between optically generated electrons and holes in the spatially separated layer is confined within the moiré trap potential and spatially organized as a moiré exciton ensemble. [9][10][11][12] The moiré trapped exciton offers high potential as a platform for many-body physics and the design of quantum optics applications, such as a dense array of coherent quantum emitters; [13,14] however, the discrete excitonic states and dynamics of the confined exciton within the moiré potential remain unexplored.…”
