The Second International Conference on Micro Nano Devices,Structure and Computing Systems(MNDSCS 2013)

作者： Yurii N.Kulchin Vladimir P.Dzyuba Valentin A.Milichko Institution of Russian Academy of Sciences Institute of Automation and Control Processes FEB RAS

The study of optical properties of AlO, SiO, TiO, and Zn O nanoparticles in weak optical fields is presented. We found that some nanoparticles have unique optical nonlinearity: The values of portions to nanoparticle refractive index and absorption coefficient increase to maxima, and then decrease to zero when the radiation intensity changes from 1 to 500 W/cm2. We estimated electron energy structures of nanoparticles and experimentally determined that such nonlinearity is directly related to peculiarities of the energy structure. We obtained a good fitting of theoretical results to the experimental ones（e.g. absorbance spectra of nanoparticles;the dependence of nanoparticle refractive index and absorption coefficient on radiation intensity）.

In this paper we propose an original functional method which allows us to determine the effect of different deviations of nano-object shape on quantum characteristics of particles localized inside the nano-object. This method is ideologically similar to the perturbation theory, but the perturbation of the surface shape, rather than potential, is used. The results of analysis the quantumsize states of particles inside the nano-object with deformed sphere shape showed that the probability density of particle location is more sensitive to shape perturbations than surface energy spectrum and quantum states density are.

In this paper, an approach for development of program-verifier whereby it is carried out a check of mission for autonomous underwater vehicle (AUV) is proposed. The approach is consisted in substitution of standard libraries, in which described access to all resources of AUV, on libraries which carry out transmit of commands and parameters of these commands to external program-verifier. The program-verifier considerably facilitate localization of logical error in mission and show state of AUV and its on-board equipments when commands execution of mission.

The phase of light propagating through a bent optical fibre is shown to depend on the refractive index of the medium surrounding the fibre cladding when there is resonance coupling between the guided core mode and cladding modes. This shifts the spectral maxima in the bent fibre-optic Fabry–Perot interferometer. The highest phase and spectral sensitivities achieved with this interferometer configuration are 0,71 and 0,077, respectively, and enable changes in the refractive index of the ambient medium down to 5·10 to be detected. This makes the proposed approach potentially attractive for producing highly stable, precision refractive index sensors capable of solving a wide range of liquid refractometry problems.

Electroluminescence properties of p-Si/β -FeSi2 NCs/../n-Si mesa diodes with embedded multilayers of β -FeSi2 nanocrystallites

Light-emitting silicon diode structures with embedded β -FeSi2 nanocrystallites have been fabricated using solid phase epitaxy and a combination of reactive deposition and solid phase epitaxy. Electroluminescence (EL) of the structures is studied over various temperatures and current densities under forward and reverse biases. We can state that β -FeSi2 NCs formed by the combined RDE+SPE method results in the formation of high density of dislocations and point defects. In contrast, defect-free structures with β -FeSi2 NCs formed by SPE demonstrate intense EL (η = 1.2×10-5%) in the wavelength range 1.4-1.6 μm even at room temperature. EL intensity dependence on the number of layers with embedded β -FeSi2 NCs is almost linear for the heterostructures formed on Si(100) and sublinear for the heterostructures formed on Si(111) substrate. The increase of the initial Fe layer thickness leads to the electroluminescence quenching. (© 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim) © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

In this paper we introduce three technological ways how to increase an absorption coefficient of hydrogenated silicon/Si:H/ thin films and diode structures on the base of Si:H. The first one is reactive deposition epitaxy (RDE), which permit to form silicide nanoparticles of different elements /Fe, Cr, Ca, Mg/ with semiconducting properties and convenient band gap. Two more simple techniques have been also tested for the creation of magnesium silicide nanoparticles (Mg2Si-NPs): a reactive laser ablation (RLA) and the combination of Mg vacuum evaporation and Plasma-Enhanced Chemical Vapour Deposition (PECVD). The formation of Mg2Si-NPs, its structures and the changes of optical absorption for samples grown by three methods have been proved by the Raman and optical spectroscopies. © 2013 WILEY-VCH Verlag GmbH & Co.
