Vortex-Beam Transient Absorption Microspectroscopy Resolves Ultrafast Free-Exciton and Polaron Diffusion in 2D Perovskites
Ju-Young Kim, Anirban Mondal, Gi Rim Han +4
Two-dimensional (2D) Ruddlesden Popper perovskites are promising optoelectronic materials with strongly confined excitonic properties; however, probing their ultrafast carrier tran…
Optical-Field Driven Charge-Transfer Modulations near Composite Nanostructures
Kwang Jin Lee, Elke Beyreuther, Sohail A. Jalil +4
Optical activation of material properties illustrates the potentials held by tuning light-matter interactions with impacts ranging from basic science to technological applications.…
Annihilation mechanism of excitons in a MoS2 monolayer through direct Förster-type energy transfer and multistep diffusion
Kwang Jin Lee, Wei Xin, Chunlei Guo
Atomically thin MoS2 layer is a direct bandgap semiconductor exhibiting strong electron-hole interaction due to the extreme quantum confinement and reduced screening of Coulomb int…
Controlling exciton dynamics in two-dimensional MoS2 on hyperbolic metamaterial-based nanophotonic platform
Kwang Jin Lee, Wei Xin, Chunhao Fann +6
The discovery of two-dimensional transition metal dichalcogenides (2D TMDs) has promised next-generation photonics and optoelectronics applications, particularly in the realm of na…
Hyperbolic Dispersion Dominant Regime Identified through Spontaneous Emission Variations near Metamaterial Interfaces
Kwang Jin Lee, Yeon Ui Lee, Sang Jun Kim +1
Surface plasmon polariton, hyberbolic dispersion of energy and momentum, and emission interference provide opportunities to control photoluminescence properties. However, the inter…
Enhanced Organic Solar Cells Efficiency through Additive Electronic and Electro-optic Effects Resulting from Doping a Polymer Hole Transport Layer
C. T. Howells, K. Marbou, H. Kim +20
We demonstrate that blending fluorinated molecules in PEDOT:PSS hole transport layers (HTL) induces charge transfers which impact on both charge extraction and photogeneration with…
