The pinning effect
Webb12 apr. 2024 · The effectiveness of the “elastic” twins effect as pinning centers was studied by measuring of the critical transport current J c in single crystals YBa 2 Cu 3 O 7–x. The presented experimental data indicate that the “elastic” twins boundaries are effective pinning centers of the magnetic flux lines in single crystals of the compound … Webb6 jan. 2024 · Pinning of screw and near screw dislocations, on the other hand, is characterized by a different type of energy minimum with much reduced pinning length and pinning displacement. Pinning stresses of near-screw dislocations are slightly lower than those of edge dislocations, but more importantly, the depth of the energy minimum for …

WebbThe metal is reduced and new electronic bandgap states are formed at the surface. As a consequence a Fermi level pinning effect occurs which results in a smaller shift of EB due to halogen adsorption and decreased photovoltages and consequently an increased double layer potential drop (Fig. 4). [Pg.129] Webb15 dec. 2024 · The effect of the interface defect states on the electrical performance of 2D devices has not been studied intensively yet. To the best of our knowledge, the effect of post-treatments on FLP in 2D devices, e.g., annealing, has also not been studied, despite the strong relationship between curable defects and FLP.
