The intrinsic carrier concentration in InSb was determined, between 246 and 370 K, by a helicon method consisting of a microwave interferometer at 34 GHz. The accuracy of the carrier concentration is between 1–2%. The influence of experimental parameters on the determination of the carrier ...
Here,nis the number of carriers,qis the ionic charge, anduis the carrier mobility. For a given system,qis definite. Therefore, there are two pathways for boosting the ionic conductivity: (1) increase the number of carriers and (2) increase the rate of carrier motion. (1) Increase the num...
In semiconductor quantum-well lasers, changes in the carrier concentration induce a corresponding proportional change in the refractive index leading to additional frequency noise through Kramers–Kroning relations13 due the asymmetric shape of the gain spectrum in this medium16. Thus, fluctuations in ...
In this regard, the first steps towards the fabrication of synthetic cells with mammalian cell cognition require the incorporation of receptors in synthetic cell membranes, utilization of building blocks with intrinsic living cell-cognate properties, and the encapsulation of chemical and enzymatic ...

1A). The percentage of complexed siRNA for varying w/w ratios was determined by spectrophotometry and calculated from the differences of siRNA amount added to the carrier and the concentration of siRNA in solutions after particle separation (Fig. 1B). Higher siRNA entrapment efficiency was observed...
The recent models of Heasell and Popovic are discussed from the unifying viewpoint that both use the deionization of impurities to try to explain the excess intrinsic carrier density (or deficit effective doping concentration) experimentally observed in heavily doped silicon. The conclusion is that ne...
The intrinsic insolubility of AlClPc in aqueous media represents certainly a drawback if systemic administration of the drug is desired. However, in case of topical application, for the treatment of non-melanoma skin cancer the aggregation of the Pc can be circumvented by the use of ...
After performing the second filtration with a cell strainer, the single-cell suspension was stained with fluorescein diacetate (FDA) at 14 mM final concentration for 3 min on ice and the number and activity of cells was calculated with microscope (ZEISS Axioscope A1). The protoplasts with a...
