    • Comparative study of the influence of the reorganization energy on the hole transport of two four-cyclic arenes 

      Kania, Sylwester; Kuliński, Janusz; Sikorski, Dominik (Wydawnictwo Politechniki ŁódzkiejLodz University of Technology. Press, 2017)
      Application of the method of quantum-mechanical calculations allowed the determination of the reorganization energy of the molecules of tetracene and p-quaterphenyl and the estimation of the transfer rate integral between ...

    • Comparison of methods for simulation of the optical properties of VCSELs 

      Więckowska, Marta; Dems, Maciej; Czyszanowski, Tomasz (Wydawnictwo Politechniki ŁódzkiejLodz University of Technology. Press, 2017)
      This paper presents the differences arising from the use of scalar (Effective Frequency Method) and vector (Fourier’s and Bessel’s Admittance Methods) calculation methods in optical analysis of arsenide Vertical-Cavity ...

    • Current dependence of resistances and capacitances in a vertical-cavity surface-emitting laser 

      Komar, Paulina; Śpiewak, Patrycja; Gębski, Marcin; Lott, James A.; Wasiak, Michał (Wydawnictwo Politechniki ŁódzkiejLodz University of Technology. Press, 2017)
      Based on the model of impedance and modulation time constants for vertical-cavity surface-emitting lasers (VCSELs) we study the resistances and capacitances of an equivalent circuit as a function of the current flowing ...

    • The effect of the dipole moment on hole conductivity of polycrystalline films of two anthracene derivatives 

      Kania, Sylwester; Kościelniak-Mucha, Barbara; Kuliński, Janusz; Słoma, Piotr; Wojciechowski, Krzysztof (Wydawnictwo Politechniki ŁódzkiejLodz University of Technology. Press, 2017)
      Hole mobility in the polycrystalline layers of anthrone and anthraquinone differs in one order of magnitude in spite of nearly the same crystalline structure. The origin of this difference was determined with use of the ...

    • Influence of tilted surface alignment on flexoelectric domains in twisted nematic layers 

      Buczkowska, Mariola; Derfel, Grzegorz (Wydawnictwo Politechniki ŁódzkiejLodz University of Technology. Press, 2017)
      The small deformations induced by electric field in twisted flexoelectric nematic layers were simulated numerically. The onedimensional (i.e. homogeneous over the whole area of the layer) and two-dimensional (i.e. ...

    • Scientific Bulletin. Physics No. 1219, vol. 38 (2017) 

      Lodz University of Technology; Politechnika Łódzka (Lodz University of Technology PressWydawnictwo Politechniki Łódzkiej, 2017)

    • Sensitivity of tetracene layer as an effect of entanglement 

      Kania, Sylwester; Kościelniak-Mucha, Barbara; Kuliński, Janusz; Słoma, Piotr; Wojciechowski, Krzysztof (Wydawnictwo Politechniki ŁódzkiejLodz University of Technology. Press, 2017)
      Application of the method of quantum-mechanical calculations allowed for studies of variability of interactions between molecules of ethanol and tetracene. Entanglement of quantum states is seen during calculations in ...

    • Subwavelength high contrast gratings as optical sensing elements 

      Marciniak, Magdalena; Gębski, Marcin; Dems, Maciej; Czyszanowski, Tomasz (Wydawnictwo Politechniki ŁódzkiejLodz University of Technology. Press, 2017)
      Subwavelength high contrast gratings (HCG) can be used as high reflective mirrors and can be used as mirrors of vertical-cavity surface-emitting lasers. HCG mirrors can be designed in such a way that they are extremely ...

    • Verification of one-dimensional models describing anisotropy of step growth 

      Izdebski, Marek; Ledzion, Rafał (Wydawnictwo Politechniki ŁódzkiejLodz University of Technology. Press, 2017)
      Models that allow to obtain directional dependencies of normal velocity of a straight step on the (001) face of Kossel crystal and its edge free energy are reviewed. The dependencies were considered in a wide range of ...
