    • Defects controlling electrical and optical properties of electrodeposited Bi doped Cu2O 

      Brandt, Iuri Stefani; Tumelero, Milton André; Martins, Cesar Augusto; Campos, Cristiani Silveira; Faccio, Ricardo; Pasa, Andre Avelino (2018) [Journal article]
      Doping leading to low electrical resistivity in electrodeposited thin films of Cu2O is a straightforward requirement for the construction of efficient electronic and energy devices. Here, Bi (7 at. %) doped Cu2O layers ...

    • Electrical conductivity in electrodeposited Cu-Ge(O) alloy films 

      Zhao, Fu; Xu, Yin; Tumelero, Milton André; Pelegrini, Silvia; Pasa, Andre Avelino; Zangari, Giovanni (2018) [Journal article]
      Integrated circuits currently use mainly copper as the interconnect material; unfortunately the ongoing miniaturization currently requires materials with higher electromigration resistance and possibly improved conductivity. ...

    • Electrodeposited Cu2O doped with Cl : electrical and optical properties 

      Pelegrini, Silvia; Tumelero, Milton André; Brandt, Iuri Stefani; Della Pace, Rafael Domingues; Faccio, Ricardo; Pasa, Andre Avelino (2018) [Journal article]
      For understanding the electrical and optical properties of electrodeposited Cl-doped Cu2O thin films, we have studied layers with increasing thickness and Cl concentrations of 0.8 and 1.2 at. %. The deposits were characterized ...

    • Extremely large magnetic-field-effects on the impedance response of TiO2 quantum dots 

      Mombrú, Dominique; Romero, Mariano; Faccio, Ricardo; Tumelero, Milton André; Mombrú, Álvaro W. (2019) [Journal article]
      Here, we report large magnetoresistance and magnetocapacitance response of undoped TiO 2 quantum dots weighting the contribution of both grain and grain boundaries by means of impedance spectroscopy. We also performed a ...

    • Morphology and Structure of Electrodeposited Prussian Blue and Prussian White Thin Films 

      Baggio, Bruna Fernanda; Vicente, Cristiano; Pelegrini, Silvia; Campos, Cristiani Silveira; Brandt, Iuri Stefani; Tumelero, Milton André; Pasa, Andre Avelino (2019) [Journal article]
      The compound Prussian Blue (PB), and its reduced form Prussian White (PW) are nowadays considered, in applied and fundamental research groups, as potential materials for sustainable energy storage devices. In this work, ...
