Advances in ultrafast plasmonics
Alemayehu Nana Koya, Marco Romanelli, Joel Kuttruff +22
In the past twenty years, we have reached a broad understanding of many light-driven phenomena in nanoscale systems. The temporal dynamics of the excited states are instead quite c…
Tunable Localized Charge Transfer Excitons in a Mixed Dimensional van der Waals Heterostructure
Mahfujur Rahaman, Emanuele Marino, Alan G. Joly +9
Observation of interlayer, charge-transfer (CT) excitons in van der Waals heterostructures (vdWHs) based on 2D-2D systems has been well investigated. While conceptually interesting…
Exciton tuning in monolayer WSe via substrate induced electron doping
Yang Pan, Mahfujur Rahaman, Lu He +8
We report on large exciton tuning in WSe monolayers via substrate induced non-degenerate doping. We observe a redshift of 62 meV for the exciton together with a 1-2 o…
Signature of lattice dynamics in twisted 2D homo/hetero-bilayers
Yang Pan, Shutong Li, Mahfujur Rahaman +2
Twisted 2D bilayer materials are created by artificial stacking of two monolayer crystal networks of 2D materials with a desired twisting angle . The material forms a moiré supe…
High Density, Localized Quantum Emitters in Strained 2D Semiconductors
Gwangwoo Kim, Hyong Min Kim, Pawan Kumar +14
Two-dimensional chalcogenide semiconductors have recently emerged as a host material for quantum emitters of single photons. While several reports on defect and strain-induced sing…
