Studies from Azerbaijan National Academy of Sciences Yield New Information about Condensed Matter (Temperature and frequency dependence of electric conductivity in nano-grained SiO2 exposed to neutron irradiation)

By a News Reporter-Staff News Editor at Physics Week -- Investigators publish new report on Condensed Matter. According to news reporting originating in Baku, Azerbaijan, by VerticalNews journalists, research stated, "We studied electric properties of SiO2 nanoparticles exposed to continuous neutron irradiation (2 x 10(13)) cm(-2) s(-1) neutron flux) for different periods up to 20 h and initial states. Electric properties of the samples before and after irradiation were studied in the 0.09 Hz-2.3 MHz frequency and 100-400 K temperature range."

The news reporters obtained a quote from the research from the Azerbaijan National Academy of Sciences, "In the experiments the samples have been irradiated by up to 20 h. It has been shown that upon increasing irradiation period, electric conductivity of the samples increases. The formation of clusters in three different states and energies at low temperatures under the neutron flux effect has been revealed."

According to the news reporters, the research concluded: "In addition, activation energy was calculated from the temperature-dependent dielectric response data using the Arrhenius expression."
