Various devices and methods of ignition and afterburning of toxic components contained in EIC burnt gases are considered as an alternative to catalytic neutralizers. Experimental investigations have been carried out on the laboratory stand with the VAZ-1111 “Oka” engine. Efficiency of introducing additional air and (or) oxygen into the burnt gases is shown.
An analysis was made of the results of investigations of the pseudodoping effect in two batches of a-Si:H samples, formed by the hf sputtering method, and investigated by a variety of techniques. A relationship was established between a change in the Fermi level position E(f) and changes in the mechanisms of condensation of SiH(n) complexes (n = 1 or 2). The limited validity of the published analyses of the relationship between the position of E(f) and the spectrum of the density of states was demonstrated. A new variant of such an analysis made it possible to obtain quantitative estimates of the shift of E(f) from the information on the content of the investigated complex in film, providing an opportunity for a direct experimental verification by spectroscopic methods.
Анализируетсяkp-метод расчета зонных структур. Обнаружены: неоднозначностя матричных элементов оператора нмпульса и неудовлетворительная картина эиергетической диаграммы в Σ-направлении, а также в некоторых других несимметричных направлениях. Предлагается: линеаризовать закох дисперсии, аппроксимировать энергетические состояния зоны проводимости соответсвующими плоскостями, использовать систему линейных уравнений, полученных из инвариантных соотношений, для подгонки параметров.
