The numerical analysis of electrical properties involved in transport mechanism such as carrier concentration, carrier mobility, carrier effective mass, electrical resistivity and electrical conductivity for some rare earth chalcogenides is discussed. The formulae are derived and used to obtain numerical values of these electrical parameters, which are useful to describe the electrical behavior...

The carrier transport properties in nanocrystalline semiconductors and organic materials play a key role for modern organic/inorganic devices such as dye-sensitized (DSC) and organic solar cells, organic and hybrid light-emitting diodes (OLEDs), organic field-effect transistors, and electrochemical sensors and displays. Carrier transport in these materials usually occurs by transitions in a bro...

A liquid-crystalline benzocrown ether, 4'-[(4''-1,1,2,2-tetrahydroperfluorooctyloxy)biphenyloxycarbonyl]benzo-15-crown-5, was used as a neutral carrier of ion-selective electrodes (ISEs) to elucidate the effect of highly ordered assembling of the neutral carrier on the sensor properties through fluorophilic interactions. The properties for the membrane and the resulting ISEs based on a benzocro...

The saturation properties of terahertz emission from biased, large-aperture photoconductors excited by trains of amplified femtosecond optical pulses are presented. A direct comparison is made of the multiple-pulse saturation properties of terahertz emission from semi-insulating GaAs and low-temperature-grown GaAs emitters with different carrier lifetimes. When the carrier lifetime is less than...

The influence of charge-carrier concentration on the magnetic properties of the semimagnetic semiconductor [(PbTe)l-x(SnTe)x]l-y[MnTe]y (x=0.72, y=O.03) is reported. Magnetization, magnetic susceptibility, and specific heat have been measured. For carrier concentrations below p = 3 x 10 cm 3 the alloy is paramagnetic. For p ~ 3 x 1020 cm 3 an abrupt transition to a fer­ romagnetic phase is obse...

We report an experimental investigation of the nonlinear optical properties of nanoporous silicon optical waveguides measured at 1550 nm. The nonlinear properties including two-photon absorption, self-phase modulation, free-carrier absorption and free-carrier plasma dispersion are characterized and compared with similar measurements conducted on a conventional silicon-on-insulator ridge wavegui...

Differential light-biased dynamic measurements of charge carrier recombination properties in semiconductors have long been known to yield only differential rather than actual recombination properties. Therefore, the determination of injection-dependent recombination properties from such measurements was previously found to require integration over the entire injection range. Recent investigatio...

acridine derivatives, especially 1,8-dioxo-9-aryl-decahydroacridine represent significant scaffolds in medicinal chemistry. given the biological properties of such products which are used in drug development, they need to have appropriate carrier. proteins are generally used as helpful tools in drug delivery. consequently, molecular docking between these compounds and bovine serum albumin (bsa)...

Dry powder inhalers (DPIs) are distinguished from one another by their unique device geometries, reflecting their distinct drug detachment mechanisms, which can be broadly classified into either aerodynamic or mechanical-based detachment forces. Accordingly, powder particles experience different aerodynamic and mechanical forces depending on the inhaler. However, the influence of carrier partic...
