Dangerous Bonds Individual of Hydrogenated Amorphous Silicon and Defect Absorption Spectra
East European Journal of Physics, 2023 In this work, defect absorption spectra for defects characteristic of hydrogenated amorphous silicon are theoretically studied. It is shown that in order to determine defect absorption spectra using the Kubo-Greenwood formula, the indefinite integral in

A new method of studying the relation between ionization rates and radio-wave absorption in polar-cap absorption events [PDF]
, 2005 International audienceDuring polar-cap absorption events, which are caused by the incidence of energetic solar protons, the high-latitude ionospheric D region is extended down to relatively low altitudes. While the incoming proton fluxes may be monitored
