Photoluminescence at 1.53 um from Er: SiN x on silicon photonic crystal cavities was extracted via fiber tapers with 2.5 x greater collection efficiency compared to free space emission. Fibers were also used to demonstrate a 10 nm tuning range of 750 nm SHG emission from GaP cavities.
Broadband terahertz modulators using self-gated graphene capacitors
Kakenov, Nurbek; Balci, Osman; Polat, Emre O.; Altan, Hakan; KOCABAŞ, COŞKUN (2015-09-01)
We demonstrate a terahertz intensity modulator using a graphene supercapacitor which consists of two large-area graphene electrodes and an electrolyte medium. The mutual electrolyte gating between the graphene electrodes provides very efficient electrostatic doping with Fermi energies of 1 eV and a charge density of 8 x 10(13) cm(-2). We show that the graphene supercapacitor yields more than 50% modulation between 0.1 and 1.4 THz with operation voltages less than 3 V. The low insertion losses, high modulati...
Radiation impedance study of a capacitive micromachined ultrasonic transducer by finite element analysis
Bayram, Barış (2015-08-01)
In this study, radiation impedance of a capacitive micromachined ultrasonic transducer composed of square-shaped membranes arranged in m x m configuration (m = 1 - 5) is investigated using finite element analysis (FEA) of a commercially available software package (ANSYS). Radiation impedance is calculated for immersed membranes operating in conventional and collapse modes. Individual membrane response within the multi-membrane configuration is analyzed, and excited modes and their effects on radiation imped...
Dielectric matrix influence on the photoluminescence properties of silicon nanocrystals
Ferraioli, L.; Cazzanelli, M.; Daldosso, N.; Mulloni, V.; Bellutti, P.; Yerci, Selçuk; Turan, Raşit; Mikhaylov, A.n.; Tetelbaum, D.ı.; Pavesi, L. (null; 2006-12-01)
Photoluminescence properties of silicon nanocrystals embedded in five different oxide matrices are analyzed. Samples are silicon rich oxide and oxynitride produced by PECVD and ion implantation and crystalline and amorphous aluminum oxide implanted with silicon.
Poly(4-styrenesulfonic acid-co-maleic acid) stabilized nickel(0) nanoparticles : highly active and cost effective catalyst in hydrogen generation from the hydrolysis of hydrazine borane
Şencanlı, Selin; Özkar, Saim; Department of Chemistry (2013)
In general, the catalytic activity of transition metal nanoparticles increases as the fraction of atoms on the surface increases with decreasing particle size. However, transition metal nanoparticles tend to agglomerate into bulk metal in solution. In order to prevent agglomeration stabilizing agent can be used in the formation of stable transition metal nanoparticles in solution. In this study, one of the most available commercial polymers was used to provide steric stabilization during the formation of st...
