Light propagation in two-layered turbid media having an infinitely thick second layer is investigated in the steady-state, frequency, and time domains. A solution of the diffusion approximation to the transport equation is derived by employing the extrapol ...
In a recent paper we measured the lateral hole diffusion in a GaAs/AlGaAs single quantum well (SQW) by a novel method. At helium temperature, we estimate a lateral hole diffusion length in the QW of 1.5 mum. However, the assumption that diffusion takes pla ...
It is shown that Te and Pb, which segregate at the surface during the epitaxial growth of GaAs, respectively, decrease and increase the surface diffusion length. This indicates that under the generic term ''surfactant,'' there are two types of surface segr ...
Oxygen diffusion is treated in a dense electronically conducting cobaltate pellet blocked ionically on one surface, electronically on the other, and sealed on its cylindrical periphery. A procedure is developed for extracting the chemical diffusion and sur ...
The concept of “mobile” and “immobile” fluid regions (as incorporated in the Two-Region Model, TRM) is often used in the governing equation to model tailing in solute breakthrough curves (BTC). In this paper, we apply the TRM and its parent equation, the A ...
Particle and heat transport in a low collisional plasma confined by a partially stochastic magnetic field are analysed. We show that the particle diffusion is ambipolar. Moreover near stochastic threshold, the electron heat diffusivity chi(e) is enhanced, ...
A method for the simultaneous production of hydrogen and oxygen from water by the visible light irradiation of a water solution containing photosensitizer, an electron relay and a suitable combination of redox catalysts. ...

Ag aggregation on Ag(111), Pt(111), and 1 ML Ag pseudomorphically grown on Pt(111), has been studied with variable temperature STM. These systems all have in common that dendritic patterns with trigonal symmetry rather than randomly ramified aggregates, wh ...
Although a rigorous definition of growth-limiting substrate relies on a kinetic anal., a simple stoichiometric anal. based on the calcn. of the conversion is more applicable. Anal. of single and dual limitations is based on a simulated example for a substr ...
Ab initio calculations on surface diffusion of Cu adatoms on Cu(001) are presented. The hopping mechanism with a calculated energy barrier of 0.69 eV is found to be favorable over the exchange mechanism with 0.97 eV. We find from the geometry relaxations t ...
