Spacer-Mediated Gold Nanocube Arrays for Edge-Localized Excitonic Enhancement in Monolayer MoS2
Abdullah Efe Yildiz, Emre Ozan Polat
The study uses numerical simulations to demonstrate that arrays of gold nanocubes, spaced from a monolayer of MoS2 by thin Al2O3 or h‑BN layers, can strongly enhance exciton genera…

Geometry-Controlled Exciton Selectivity in Monolayer MoS2 Using Plasmonic Hollow Nanocavities
Abdullah Efe Yildiz, Emre Ozan Polat
Spectral control of closely spaced excitonic transitions is central to valleytronic photonics, nanoscale light sources, and wavelength-encoded sensing. In monolayer molybdenum disu…

Toroidal Plasmonic Nanodimers for Enhanced Near-Infrared Emission in Heterostructured InP Quantum Dots
Arda Gulucu, Emre Ozan Polat
Near-infrared (NIR) emitters operating in the 650-900 nm range are highly attractive for imaging and sensing in turbid media; however, cadmium-free InP-based quantum dots (QDs) oft…
