Initial stages of graphitization on SiC(000-1), as studied by phase atomic force microscopy

F.J. Ferrer, E. Moreau, D. Vignaud, D. Deresmes, S. Godey, X. Wallart

The initial stages of graphitization on 4H- and 6H-SiC (000-1) under ultrahigh vacuum at temperatures of 1125–1175°C have been studied by atomic force microscopy (AFM), X-ray photoemission spectroscopy and reflected high energy electron diffraction. A progressive coverage of the surface by graphene…

Squeezing radiation from quantum cascade lasers with leaky waves

Miguel Beruete, Tahsin Akalin, Miguel Navarro-Cia, Guillaume Ducournau, Jean-Francois Lampin, Mario Sorolla

Several flat antennas consisting of a central slot surrounded by a metallic periodic structure are proposed to enhance the radiation of quantum cascade laser terahertz sources. A simulation study of the optimal profile for high gain and radiation efficiency is done. Prototypes are being fabricated

Study of enhanced biosensors based on 2-D sandwiched plasmon photonic crystals

Jin-Ying Zhang, He Huang, Wei-Jiang Xu, Julien Carlier, X.M. Ji, Bertrand Nongaillard, J. Zhou, Y.P. Huang

A novel sandwich structure of photonic crystal with periodic square array of hexagon holes was fabricated. The infrared optical properties in reflectance of the devices were tested. A sharp peak of surface plasmon resonance was observed at the incident angles of 30°. By the comparison of the…

Fabrication and characterization of half-Kerfed LiNbO3-based high-frequency (>100MHz) ultrasonic array transducers

Jin-Ying Zhang, Wei-Jiang Xu, Julien Carlier, X.M. Ji, Bertrand Nongaillard, S. Queste, J. Zhou, Y.P. Huang

The effect of kerf depth is investigated on the performances of array transducers. A finite element tool, COMSOL, is employed to simulate the properties of acoustic field and to calculate the electrical properties of the arrays, including crosstalk effect and electrical impedance. Furthermore,…
