Mie Sensing with Neural Networks: Recognition of Nano-Object Parameters, the Invisibility Point, and Restricted Models
Artur Movsesyan, Lucas V. Besteiro, Zhiming Wang +1
In this work, we use artificial neural networks (ANNs) to recognize the material composition, sizes of nanoparticles and their concentrations in different media with high accuracy,…
Temporal plasmonics: Fano and Rabi regimes in the time domain in metal nanostructures
Oscar Ávalos-Ovando, Lucas V. Besteiro, Zhiming Wang +1
The Fano and Rabi models represent remarkably common effects in optics. Here we study the coherent time dynamics of plasmonic systems exhibiting Fano and Rabi resonances. We demons…
Broadband mid-infrared perfect absorber using fractal Gosper curve
Jihua Zou, Peng Yu, Wenhao Wang +10
Designing broadband metamaterial perfect absorbers is challenging due to the intrinsically narrow bandwidth of surface plasmon resonances. Here, the paper reports an ultra-broadban…
Chiral plasmonic nanocrystals for generation of hot electrons: towards polarization-sensitive photochemistry
Tianji Liu, Lucas V. Besteiro, Tim Liedl +3
The use of biomaterials - with techniques such as DNA-directed assembly or bio-directed synthesis - can surpass top-down fabrication techniques in creating plasmonic superstructure…
Extreme multiexciton emission from deterministically assembled single emitter subwavelength plasmonic patch antennas
Amit Raj Dhawan, Cherif Belacel, Juan U. Esparza-Villa +8
Plasmonic antennas are attractive optical structures for many applications in nano and quantum technologies. By providing enhanced interaction between a nanoemitter and light, they…
Bright Luminescent Surface States on the Edges of Wide-bandgap Two-dimensional Lead Halide Perovskite
Yanan Wang, Chong Wang, Xinghua Su +9
Three-dimensional lead halide perovskites have surprised people for their defect-tolerant electronic and optical properties, two-dimensional lead halide layered structures exhibit…
Mid-infrared Plasmonic Circular Dichroism Generated by Graphene Nanodisk Assemblies
Xiang-Tian Kong, Runbo Zhao, Zhiming Wang +1
It is very interesting to bring plasmonic circular dichroism spectroscopy to the mid-infrared spectral interval, and there are two reasons for this. This spectral interval is very…
Understanding Hot-Electron Generation and Plasmon Relaxation in Metal Nanocrystals: Quantum and Classical Mechanisms
Lucas V. Besteiro, Xiang-Tian Kong, Zhiming Wang +2
Generation of energetic (hot) electrons is an intrinsic property of any plasmonic nanostructure under illumination. Simultaneously, a striking advantage of metal nanocrystals over…
Aluminum Nanoparticles with Hot Spots for Plasmon-Induced Circular Dichroism of Chiral Molecules in the UV Spectral Interval
Lucas V. Besteiro, Hui Zhang, Jérôme Plain +3
Plasmonic nanocrystals with hot spots are able to localize optical energy in small spaces. In such physical systems, near-field interactions between molecules and plasmons can beco…
Plasmonic Nanostars with Hot Spots for Efficient Generation of Hot Electrons under Solar Illumination
Xiang-Tian Kong, Zhiming Wang, Alexander O. Govorov
Nanostars (NSTs) are spiky nanocrystals with plasmonic hot spots. In this study, we show that strong electromagnetic fields localized in the nanostar tips are able to generate larg…
Localization of Temperature Using Plasmonic Hot Spots in Metal Nanostructures: The Nano-Optical Antenna Approach and Fano Effect
Larousse Khosravi Khorashad, Lucas V. Besteiro, Zhiming Wang +2
It is challenging to strongly localize temperature in small volumes because heat transfer is a diffusive process. Here we show how to overcome this limitation using electrodynamic…
