Impact of the particles impingement on the electronic conductivity of Al doped ZnO films grown by reactive magnetron sputtering
(IOP Science, 2010)
Aluminium doped zinc oxide thin films (4 at.% Al) were deposited by reactive magnetron sputtering technique and characterized by X-ray diffraction (XRD), Rutherford backscattering spectroscopy (RBS), four point probe ...

Effect of breather existence on reconstructive transformations in mica muscovite
(2008)
Reconstructive transformations of layered silicates as mica muscovite take place at much lower temperatures than expected. A possible explanation is the existence of breathers within the potassium layer. Numerical analysis ...

Ratchet effect in solids: Defect transport driven by biharmonic forces
(2007)
Interstitials and vacancies, in one-dimensional lattices, are point defects that can be modelled by means of kinks or antikinks in a discrete Frenkel-Kontorova model, with a sine-Gordon on-site potential. The properties ...

Overdamped deterministic ratchets driven by multifrequency forces
(Jagellonian University, Cracow, 2006)
We investigate a dissipative, deterministic ratchet model in the overdamped regime driven by a rectangular force. Extensive numerical calculations are presented in a diagram depicting the drift velocity as a function of a ...
