We report on the effect of anisotropy on the step meandering instability on vicinal surfaces during molecular beam epitaxy growth. A scenario of interrupted coarsening is found: the lateral length scale of the structure first significantly increases with time and then freezes at a larger length scale. The wavelength selection mechanism results from a nontrivial nonlinear effect of anisotropy. A...

The Graphene based single electron transistor (SET) as a coulomb blockade device need to be explored .It is a unique device for high-speed operation in a nano scale regime. A single electron transfers via the coulomb barriers, but its movement may be prevented by coulomb blockade, so its effect is investigated in this research. The conditions of coulomb blockade and its controlling factors such...

We reanalyse theoretical considerations and experimental data, in an attempt to decide whether there is another scale in the fractional quantum Hall effect problem, in addition to the magnetic scale defined by the magnetic length a c or the cyclotron energy ¯ hω c. We then discuss possible implications of a new scale on the formulation of a theoretical model of the fractional quantum Hall effect.

This paper starts from the hypothesis that streetscapes with shorter façade lengths are more pleasant for pedestrians than long and monotonous façades. It analyses four case studies where short were implemented by applying different means of regulation gives insight into an experimental planning example Schlieren, Switzerland. Through investigation these cases, possibilities to regulate length ...
