Effect of pressure on the properties of Al-SiO2-n-Si<Ni> structures

Abstract

We investigated the effect of hydrostatic pressure on relaxation characteristics of the three-layer Al SiO Ni Sin Al 2    structures. It was found that 20 min exposure to a pressure of 8 kbars results in reduction of the integral density of surface states, while exerting no influence on the generation centers in the bulk.

Code development for the calculations of time-dependent multimode oscillations in the cavity of the future high-power gyrotrons

“…The boundary conditions for Eq. (3) are radiation boundary conditions [9,10] with zero reflection at the frequency nm: ( 5 ) where zin and zout are the z-coordinates at the input and output of the resonator, respectively. The boundary condition at zin was used to determine the starting value of the derivative of Vnm for the integration of the equations.…”

“…As discussed in Ref. 9, these conditions assume that the cavity cross section is far from critical and is weakly varying in the end. In the present study, we used the electron motion in terms of the adiabatic approximation and the nonlinear equations of motion for an electron in a thin annular beam satisfied by P and uz [1].…”

Ультразвуковое Воздействие На Генерационно-Рекомбинационные Свойства Межфазной Границы МДП Структур

“…Целью настоящей работы является исследование влияния ультразвукового воздействия на плотность электронных состояний, локализованных на межфазной границе раздела Si-стекло. [11]. Значения C(t) можно найти для каждого момента времени t из экспериментальной релаксационной характеристики структуры МДП, используя выражение (7) указанной работы:…”
