Electrical and dielectrical properties of composites based on (Ag1–xCux)7GeS5I mixed crystals
Journal Title: Semiconductor Physics, Quantum Electronics and Optoelectronics - Year 2018, Vol 21, Issue 4
Abstract
Polymer composites were prepared from (Ag 1–x Cu x ) 7 GeS 5 I mixed crystals grown using Bridgman–Stockbarger method. The impedance measurements were performed at room temperature in the frequency range 10 –3 –2·10 6 Hz. The frequency dependences of electrical conductivity and dielectric permittivity for composites based on (Ag 1–x Cu x ) 7 GeS 5 I mixed crystals were obtained. The Nyquist plots for (Ag 1–x Cu x ) 7 GeS 5 I-based composite has been analyzed. The influence of cation Ag→Cu substitution on electrical conductivity of composites based on (Ag 1–x Cu x ) 7 GeS 5 I mixed crystals has been studied.

Impact of semiconductor quantum dots bandgap on reabsorption in luminescent concentrator
We have investigated the influence of the average radius and its dispersion of the semiconductor quantum dots (QDs) used in luminescent solar concentrators (LSCs) on reabsorption. To minimize the detrimental reabsorption...
Search of mode wavelengths in planar waveguides by using Fourier transform of wave equation
The article describes a numerical method based on Fourier transform for studying propagating optical waves in dielectric planar waveguides. The inverse problem to the known direct one in waveguide investigation is propos...
Micro- and nanostructuring of metal surfaces with polarized femtosecond laser pulses
Under irradiation of the surface of metals with femtosecond laser pulses, periodic surface micro- and nanostructures have been obtained. The dependence of orientation inherent to formed structures on direction of the ele...
Van der Waals interaction between surface and particle with giant polarizability
We show that a nanoparticle with a “giant” polarizability (i.e., with the polarizability volume significantly exceeding the particle volume) placed in the vicinity of a surface experiences a strongly increased van der Wa...
Electron transport through nanocomposite SiO2(Si) films containing Si nanocrystals
The current transport through insulating SiO2 films with silicon nanocrystals in Si/SiO2(Si)/Al structures has been investigated in the wide range of temperatures (82…350 K). The nanocomposite SiO2(Si) films containing t...
