Влияние отжига на оптические свойства пленок, полученных на установке “ПФ-4”
Investigated the effect of annealing on the optical properties of metallic films obtained by setting the plasma-focus "PF-4" on glass substrates. The transmission spectra of these films before and after annealing in air at about 900 K for about 10 minutes. Shows the effect of carbon on the optical properties and electrical conductivity of the films.
The contribution of electron–phonon scattering to conductivity of a quantum cylinder in a lon-gitudinal magnetic field has been studied. It has been shown that the conductivity of the nanotube undergoes Aharonov–Bohm oscillations with variations in the magnetic flux through the nanotube cross section. The formulas describing the temperature dependence of the resistance of the nanostructure both in the case of an isotropic phonon spectrum and with allowance for the effects of phonon confinement have been obtained in the analytical form.

Radiation response of bipolar devices irradiated under various electrical modes and dose rates at high doses has been studied. A nonlinear numerical model including ELDRS effects and electric field reduction at high doses has been developed and validated. Dose degradation of a bipolar transistor's gain factor at different dose rates and electrical modes has been simulated and explained in a unified way, based on dependence of the charge yield in isolation oxides on dose rates and electric fields. It has been shown that at high doses one needs to use a nonlinear, self-consistent numerical approach, accounting for simultaneous suppression of the oxide electric field induced by trapped charge. Correspondingly, two types of degradation saturation have been revealed: (i) due to simultaneous thermal annealing, and (ii) due to total dose dependent electric field reduction in oxides. The former implies proportionality of the saturation dose and degradation level to dose rate, the latter permits dose rate independent saturation levels of degradation.
A contribution of the electron-phonon scattering to the conductivity of a quantum cylinder in a magnetic field is calculated. It is demonstrated that the nanotube conductivity undergoes the Aharonov–Bohm oscillations with changes of the magnetic flux through the nanotube cross section.
Method of in-situ X-ray reflectivity is presented. The results of investigation of titanium and silicon thin films in real-time of their deposition on silicon substrates are discussed.
