Multiperiodic nanohole array for high precision sensing
In this article, we present a multiperiodic nanohole array structure for improved sensing. The structure consists a series of rows of nanoholes, each having a different period in an ascending order. A monochromatic source illuminates the structure, and a

The conversion of sunlight into electricity by photovoltaics is currently a mature science and the foundation of a lucrative industry. In conventional excitonic solar cells, electron-hole pairs are generated by light absorption in a semiconductor and separated by the "built in" potential resulting from charge transfer accompanying Fermi-level ...

Plasmonics and metamaterials have attracted considerable attention over the past decade, owing to the revolutionary impacts that they bring to both the fundamental physics and practical applications in multiple disciplines. Although the two fields initially advanced along their individual trajectories in parallel, they started to interfere with each ...

Plasmonics in Semiconductors [PDF]
This thesis establishes a mathematical, physical and experimental framework for description, characterization, and application of semiconductor plasmonic properties. Plasmonic phenomena in semiconductors are found in the Terahertz and far-infrared domain,

All‐Optical Reconfigurable Physical Unclonable Function for Sustainable Security
An all‐optical reconfigurable physical unclonable function (PUF) is demonstrated using plasmonic coupling–induced sintering of optically trapped gold nanoparticles, where Brownian motion serves as a robust entropy source. The resulting optical PUF exhibits high encoding density, strong resistance to modeling attacks, and practical authentication ...

Abstract Since holography yields exact results, even in situations where perturbation theory is not applicable, it is an ideal framework for modeling strongly correlated systems. We extend previous holographic methods to take the dynamical charge response into account and use this to perform the first holographic computation of the

Quantumcoherent plasmonics : Atomicphasecoherence assisted surface plasmon resonance and negative optical parameters in multilevel media [PDF]
Phase coherence in atoms and semiconductor quantum dots driven by light fields are extremely sensitive to probe field frequency, and the corresponding optical responses can be controllably manipulated by the applied external control light fields (i.e ...
