Reconfigurable, non-volatile control of optical anisotropy in ReS2 via ferroelectric gating
Mahfujur Rahaman, Seunguk Song, Aaliyah C. Khan +8
Electrically tunable linear dichroism (LD) with non-volatile properties represents a critical yet elusive feature for next-generation integrated photonic elements in practical devi…
Giant Optical Anisotropy in 2D Metal-Organic Chalcogenates
Bongjun Choi, Kiyoung Jo, Mahfujur Rahaman +6
Optical anisotropy is a fundamental attribute of some crystalline materials and is quantified via birefringence. A birefringent crystal not only gives rise to asymmetrical light pr…
Highly tunable room-temperature plexcitons in monolayer WSe2 /gap-plasmon nanocavities
Thomas P. Darlington, Mahfujur Rahaman, Kevin W. C. Kwock +16
The advancement of quantum photonic technologies relies on the ability to precisely control the degrees of freedom of optically active states. Here, we realize real-time, room-temp…
Tailoring Exciton Dynamics in TMDC Heterobilayers in the Quantum Plasmonic Regime
Mahfujur Rahaman, Gwangwoo Kim, Kyung Yeol Ma +3
Control of excitons in transition metal dichalcogenides (TMDCs) and their heterostructures is fundamentally interesting for tailoring light-matter interactions and exploring their…
Wafer-scale growth of two-dimensional, phase-pure InSe
Seunguk Song, Sungho Jeon, Mahfujur Rahaman +12
Two-dimensional (2D) indium monoselenide (InSe) has attracted significant attention as a III-VI two-dimensional semiconductor (2D) with a combination of favorable attributes from I…
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…
Radiative Decay of Dark Exciton Related Emission in a Sandwiched Monolayer WSe2 Revealed by Room Temperature Micro and Nano Photoluminescence
Mahfujur Rahaman, Oleksandr Selyshchev, Yang Pan +5
TMDCs have attracted a lot of attention in recent years due to their unique indirect to direct band gap transition from bulk to monolayer thickness. Strong confinement in the out-o…
