Temperature dependence and stability of surface structures
Several years ago, Burton and Jura' reported a calculation that was based on an Einstein model and that predicted a structural phase transition for the (100) surface of Ar. On the basis of this calculation, one might expect to be able to observe such a surface phase transition in noble-gas solids and other fcc materials, such as Al and Ni. We show in Fig. 1(a) the unrearranged fcc (100) surface...
متن کاملthe study of bright and surface discrete cavity solitons dynamics in saturable nonlinear media
امروزه سالیتون ها بعنوان امواج جایگزیده ای که تحت شرایط خاص بدون تغییر شکل در محیط منتشر می-شوند، زمینه مطالعات گسترده ای در حوزه اپتیک غیرخطی هستند. در این راستا توجه به پدیده پراش گسسته، که بعنوان عامل پهن شدگی باریکه نوری در آرایه ای از موجبرهای جفت شده، ظاهر می گردد، ضروری است، زیرا سالیتون های گسسته از خنثی شدن پراش گسسته در این سیستم ها بوسیله عوامل غیرخطی بوجود می آیند. گسستگی سیستم عامل...
Dependence of surface stress, surface energy and surface tension on potential and charge.
A toy model and simple model functions are used to exemplify the relation between surface tension, surface energy and surface stress given by Shuttleworth's equation. Variations of the surface tension of charged interfaces must obey Lippmann's equation. Variations Deltaf of the surface stress of electrodes would be either equal to or proportional to and smaller than those variations Deltagamma ...
متن کاملBounds on Surface Stress-Driven Shear Flow
The background method is adapted to derive rigorous limits on surface speeds and bulk energy dissipation for shear stress driven flow in two and three dimensional channels. By-products of the analysis are nonlinear energy stability results for plane Couette flow with a shear stress boundary condition: when the applied stress is gauged by a dimensionless Grashoff number Gr, the critical Gr for e...
متن کاملResidual Stress and Surface Energy of Sputtered TiN Films
Morphology, structure, residual stress, and surface energy of magnetron-sputtered titanium nitride (TiN) thin films, deposited at 300 C with a thickness in the 0.5-1.7 lm range, were characterized. Film microstructure, the origin of residual stress, and its effect on the surface energy were analyzed. The grain size increased with the film thickness. X-ray diffraction showed (200) to (111) prefe...
