    • openAccess   Charge transport in organic semiconductors with application to optoelectronic devices 

      Montero Martín, Jose María Universitat Jaume I (2010-10-04)
      El estudio del transporte de carga en semiconductores orgánicos contribuye al desarrollo y optimización de LEDs orgánicos y nuevas células solares. En OLEDs de un sólo portador se ha encontrado una fórmula explícita de la ...

    • openAccess   Estudio de los procesos de intercalación en materiales electrómicos (a-WO3, polímeros conductores y viológenos) 

      García Cañadas, Jorge Universitat Jaume I (2006-10-06)
      This thesis presents thermodynamic studies performed by electrochemical methods (cyclic voltammetry, electrochemical impedance and chronopotenciometry) in three of the most important electrochromic materials: a-WO3, ...

    • closedAccess   Ideal Impedance Spectroscopy Equivalent Circuits for Thermoelectric Materials and Devices 

      García-Cañadas, Jorge; Beltrán-Pitarch, Braulio IEEE (2022-09)
      Impedance spectroscopy has been intensively developed in the last years in the field of thermoelectric materials. Current impedance models collect in high detail all the processes that occur in thermoelectric devices. In ...

    • openAccess   Improvement in varistor properties of CaCu3Ti4O12 ceramics by chromium addition 

      Grzebielucka, Edson; Monteiro, Joao Frederico; Souza, Eder; Borges, Christiane Philippini Ferreira; Chaves de Andrade, André Vitor; Cordoncillo, Eloisa; Beltrán Mir, Héctor; Masetto Antunes, Sandra Regina Elsevier (2019-11-17)
      The effect of chromium addition on the structure and electrical properties of CaCu3Ti4O12 is studied. Compositions based on the formula CaCu3Ti4-xCrxO12-δ (x = 0, 0.025, 0.050 and 0.075 mol%) are prepared by solid-state ...

    • openAccess   Operation Mechanism of Perovskite Quantum Dot Solar Cells Probed by Impedance Spectroscopy 

      Zolfaghari, Zahra; Hassanabadi, Ehsan; Pitarch-Tena, Didac; YOON, SEOG JOON; Shariatinia, Zahra; van de Lagemaat, Jao; Luther, Joseph M.; Mora-Sero, Ivan American Chemical Society (2018)
      We fabricated perovskite quantum dot solar cells (PQDSCs) and varied the thickness of the QD layer by controlling the number of deposition cycles; the cells were systematically investigated with impedance spectroscopy. ...

    • openAccess   Organohalide Perovskites are Fast Ionic Conductors 

      Vicente-Agut, Nuria; Garcia-Belmonte, Germà Wiley (2017-10-11)
      Fast ionic conductors constitute a family of materials exhibiting high values of the ionic conductivity while their crystal structure remains rather rigid. Perovskite-like compounds are known to be good ionic conductors ...
