Abstract
The influence of radiation factor upon formation of nano-dimensional filaments in silicon structures with their application in 3G solar cells is considered. Under the influence of hard particle radiation during some time there are accumulated failures of the structure of
We address changes in the global electric circuit, which were caused by arrival of the giant gamma flare from SGR 1806-20 to the dayside of the globe. It is shown that a parametric source of radio emission depends on the structure of the global electric circuit. We consider the formation of a discrete radio pulse in the framework of realistic exponential height profile of air resistance. We show that altitudes around the tropopause play a significant role in pulse formation. Spectral density radiated is inversely proportional to the frequency. Waveforms are computed of a parametric pulse caused by the gamma rays arrival.
KEY WORDS: Earth–ionosphere cavity, global electric circuit, the Schumann resonance, ELF bursts, gamma burst
