Time-resolved photoluminescence from porous silicon coated with a diamondlike carbon film is investigated. The intensity of
the photoluminescence from the carbon film is obserd to increase after deposition, and there is an accompanying change in
the intensity and a shortwavelength shift of the photoluminescence band of porous silicon that depends on the porosity of
its original layers. These changes are explained by the formation of carbon nanoclusters on the surface of the silicon filaments.

Three main schemes of limit theorems for random evolutions are discussed: averaging, diffusion approximation, and the asymptotics
of large deviations. Markov stochastic evolutions with locally independent increments on increasing time intervals T
ε
= t/ε → ∞, ε → 0, are considered. The asymptotic behavior of random evolutions is investigated with the use of solutions of the singular perturbation
problems for reducibly invertible operators. 相似文献
