    • Comparison of pulsed electroacoustic and thermally stimulated depolarization current measurements of thermally poled PET electrets 

      Parsa, Seyedeh Elaheh; Cañadas Lorenzo, Juan Carlos; Diego Vives, José Antonio; Mudarra López, Miguel; Sellarès González, Jordi (Elsevier, 2022-09-01)
      Article
      Open Access
      We have compared measurements of a set of polyethylene terephthalate (PET) electret samples by means of pulsed electroacoustic method (PEA) and thermally stimulated depolarization current (TSDC) techniques. Samples where ...
    • Effects of UV radiation on the charge trapping capability of PET 

      Cañadas Lorenzo, Juan Carlos; Diego Vives, José Antonio; Mudarra López, Miguel; Parsa, Seyedeh Elaheh; Sellarès González, Jordi (Institute of Physics (IOP), 2019-02-06)
      Article
      Open Access
      Poly(ethylene terephthalate) (PET) is able to retain space charge in traps, as is usual in dielectric materials. This allows the material to attain an almost permanent polarization when space charge is displaced by an ...
    • Evaluation of the LIPP method for determining the space charge profile in poled dielectrics 

      Parsa, Seyedeh Elaheh (Universitat Politècnica de Catalunya, 2013-12-11)
      Master thesis
      Open Access
      [ANGLÈS] The determination of the charge profile in corona-poled or electrode-poled samples is a key step in many dielectric studies. The purpose of this work is to evaluate the feasibility of developing a laser induced ...
    • Study of the charge profile of thermally poled electrets 

      Parsa, Seyedeh Elaheh; Trull Silvestre, José Francisco; Colom Fajula, Xavier; Sellarès González, Jordi (2016-02-17)
      Research report
      Open Access
      The charge profile of thermally poled electrets has been studied using two different methods, laser induced pressure pulse (LIPP) and pulsed electroacoustic (PEA), to gain insight into the mechanisms that are activated and ...
