Analysis of trap states in AlGaN/GaN self-switching diodes via impedance measurements

E. Perez-Martin, D. Vaquero, H. Sanchez-Martin, Christophe Gaquière, V. J. Raposo, T. Gonzalez, J. Mateos, I. Iniguez-De-La-Torre

The presence of trap states in self-switching diodes (SSD) based on an AlGaN/GaN heterojunction has been identified by means of their AC characterization between 75 kHz to 30 MHz in a wide temperature range, from 80 K to 300 K. Measurements allow us to determine two different characteristic…

Design of silver nanoparticles with graphene coatings layers used for LSPR biosensor applications

Mohamed El Barghouti, Abdellatif Akjouj, Abdellah Mir

A new hybrid graphene nanoplasmonic structure, using silver nanoparticles (AgNPs) coated with a graphene film and deposited on a substrate is proposed in this paper. The aim is to obtain a plasmonic response with high sensitivity for plasmonic biosensors. We show, through the calculation of…

p Orbital Flat Band and Dirac Cone in the Electronic Honeycomb Lattice Article

Thomas S Gardenier, Jette J van den Broeke, Jesper R Moes, Ingmar Swart, Christophe Delerue, Marlou R Slot, C Morais Smith, Daniel Vanmaekelbergh

Theory anticipates that the in-plane p x , p y orbitals in a honeycomb lattice lead to potentially useful quantum electronic phases. So far, p orbital bands were only realized for cold atoms in optical lattices and for light and exciton-polaritons in photonic crystals. For electrons, in-plane p…

Generalized elastodynamic model for nanophotonics

José Vicente Álvarez Carrera, Bahram Djafari-Rouhani, Daniel Torrent

A self-consistent theory for the classical description of the interaction of light and matter at the nanoscale is presented, which takes into account spatial dispersion. Up to now, the Maxwell equations in nanostructured materials with spatial dispersion have been solved by the introduction of the…
