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. Webb5 apr. 2024 · The pinning effect plays an important role in many fluidic systems but remains poorly understood, especially at the nanoscale. In this study, we measured the contact angles of glycerol nanodroplets on three different substrates using atomic force microscopy. By comparison of the shapes of the three-dimensional images of droplets, …
WebbIn general, the pinning effect can be characterized as (i) microscopic behavior when a droplet is pinned and the contact angle increases/decreases as the droplet volume increases/decreases and (ii) macroscopic behavior as the pinning effects decrease and ultimately, disappear with the increase of the droplet size. 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 …
