TL;DR: In this article, an innovative pump-probe technique for the determination of free carrier absorption, diffusivity, and internal quantum efficiency in Si was demonstrated, and the internal quantum efficiencies for excitation by 800 nm, 400 nm, and 267 nm were found to be 1.00, 1.25, and 1.69 × 10−17 cm2, respectively.
Abstract: We demonstrate an innovative pump-probe technique for the determination of free carrier absorption, diffusivity, and internal quantum efficiency in Si. The internal quantum efficiencies for excitation by 800 nm, 400 nm, and 267 nm light are found to be 1.00, 1.00, and 1.25, respectively. The free carrier absorption cross section at 1510 nm is determined to be σFCA = 1.69 × 10−17 cm2 and an increased value is observed for high carrier concentrations. A model for free carrier diffusion and absorption is used to extract the relationship between σFCA and carrier concentration.

TL;DR: In this article, the thermal energy band gap, the intrinsic carrier concentration, the electron and hole mobilities and the mobility ratio of intrinsic PtSb2, were derived from Hall coefficient and resistivity measurements in the mixed conduction range (77-300°K).

TL;DR: In this paper, a model based on the mass action law for the prediction of multicomponent ion exchange equilibria is developed, where ideal behavior for both the solution and the solid phase and the existence of a distribution of functional groups with different adsorption energies (and then equilibrium constant) are assumed.

01 Jan 2005TL;DR: In this article, the mass action law (MSA-MAL) approach for ion and ion-dipole models is used to revise the concept of ion association in the theory of electrolyte solutions.
Abstract: Analytical solution of the associative mean spherical approximation (AMSA) and the modified version of the mean spherical approximation — the mass action law (MSA-MAL) approach for ion and ion-dipole models are used to revise the concept of ion association in the theory of electrolyte solutions. In the considered approach in contrast to the traditional one both free and associated ion electrostatic contributions are taken into account and therefore the revised version of ion association concept is correct for weak and strong regimes of ion association. It is shown that AMSA theory is more preferable for the description of thermodynamic properties while the modified version of the MSA-MAL theory is more useful for the description of electrical properties. The capabilities of the developed approaches are illustrated by the description of thermodynamic and transport properties of electrolyte solutions in weakly polar solvents. The proposed theory is applied to explain the anomalous properties of electrical double layer in a low temperature region and for the treatment of the effect of electrolyte on the rate of intramolecular electron transfer. The revised concept of ion association is also used to describe the concentration dependence of dielectric constant in electrolyte solutions.
