Molecular Dynamics Simulations of Atomic H Etching SiC Surface

In this paper, molecular dynamics simulations were performed to study interactions between atomic H and SiC, silicon carbon surfaces were continuously bombarded by atomic H with different energies. The Tersoff-Brenner potentials were implemented. The simulation results show that with increasing incident energy, the retention rate of H atoms on the surface increases linerly. A large number of H ...

Effect of atomic-scale surface roughness on friction: a molecular dynamics study of diamond surfaces

We have examined by molecular dynamics simulations the friction which arises when two hydrogen-te~inated diamond (111) surfaces are placed in sliding contact. In particular, the effects of load, crystallographic sliding direction, and substitution of surface hydrogen groups by methyl groups on the friction coefkient p were investigated. For the hydrogen-terminated system, it is possible to have...

the 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...
