    In this study, a metal-insulator-metal capacitor structure is fabricated using polystyrene nanoparticles. Impedance spectroscopy is used to evaluate the performance of this capacitor in which we found a significant magnitude ...

  • Exploration of intercell wireless millimeter-wave communication in the landscape of intelligent metasurfaces 

    Tasolamprou, Anna; Pitilakis, Alexandros; Abadal Cavallé, Sergi; Tsilipakos, Odysseas; Timoneda, Xavier; Taghvaee, Hamidreza; Mirmoosa, Mohammad Sajjad; Liu, Fu; Liaskos, Christos; Tsioliaridou, Ageliki; Ioannidis, Sotiris; Kantartzis, Nikolaos V.; Manessis, Dionyssios; Cabellos Aparicio, Alberto; Alarcón Cot, Eduardo José (Institute of Electrical and Electronics Engineers (IEEE), 2019-01-01)
    Article
    Open Access
    Software-defined metasurfaces are electromagnetically ultra-thin, artificial components thatcan provide engineered and externally controllable functionalities. The control over these functionalities isenabled by the ...

  • Optimal voltage-support control for distributed generation inverters in RL grid-faulty networks 

    Garnica López, Miguel Andrés; García de Vicuña Muñoz de la Nava, José Luis; Miret Tomàs, Jaume; Castilla Fernández, Miguel; Guzmán Solà, Ramon (Institute of Electrical and Electronics Engineers (IEEE), 2019-10-30)
    Article
    Open Access
    During grid faults, the stability and reliability of the network are compromised, and the risk of a widespread disconnection of distributed generation power facilities is increased. Distributed generation inverters must ...

  • Beyond the required LISA free-fall performance: new LISA pathfinder results down to 20 mu Hz 

    Armano, M.; Audley, H.; Baird, J.; Binetruy, P.; Ramos Castro, Juan José (American Institute of Physics (AIP), 2018-02-05)
    Article
    Open Access
    In the months since the publication of the first results, the noise performance of LISA Pathfinder has improved because of reduced Brownian noise due to the continued decrease in pressure around the test masses, from a ...

  • LISA pathfinder performance confirmed in an open-loop configuration: results from the free-fall actuation mode 

    Armano, M.; Audley, H.; Baird, J.; Binetruy, P.; Born, M.; Bortoluzzi, D.; Ramos Castro, Juan José (American Institute of Physics (AIP), 2019-09-11)
    Article
    Open Access
    We report on the results of the LISA Pathfinder (LPF) free-fall mode experiment, in which the control force needed to compensate the quasistatic differential force acting on two test masses is applied intermittently as a ...

  • Near 5% DMSO is the best: a structural investigation of PEDOT: PSS thin films with strong emphasis on surface and interface for hybrid solar cell 

    Mahato, Somnath; Puigdollers i González, Joaquim; Voz Sánchez, Cristóbal; Mukhopadhyay, Mala; Mukherjee, Manabendra; Hazra, Satyajit (2019-09-10)
    Article

    Effect of dimethyl sulfoxide (DMSO) doping on poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS) thin films have been optimized for obtaining better hole transport layer in hybrid solar cell. The correlation ...

  • Postbond test of through-silicon vias with resistive open defects 

    Rodríguez Montañés, Rosa; Arumi Delgado, Daniel; Figueras Pàmies, Joan (2019-07-17)
    Article
    Open Access
    Through-silicon vias (TSVs) technology has attracted industry interest as a way to achieve high bandwidth, and short interconnect delays in nanometer three-dimensional integrated circuits (3-D ICs). However, TSVs are ...
