Results of direct laser recording on a two-component medium consisting of deposited layers of amorphous silicon and silver on a glass substrate by magnetron sputtering are presented. A single-mode semiconductor laser with λ = 405 nm for amorphous silicon film on glass substrate with a power of 120 mW is used for direct laser recording on amorphous silicon. Formation of the relief on the silver film with direct recording pulses of a semiconductor laser with λ = 405 nm at the a-Si layer is taken on the electron microscope TESCAN VEGA 3 LMH.

This paper presents the results of direct laser recording on a two-layer amorphous silicon / silver structure deposited on a glass substrate by magnetron sputtering. The absorption spectra of a-Si films of various thicknesses and a glass substrate are investigated. A method is proposed for direct laser recording of microstructures by focused radiation of a single-mode semiconductor laser with a wavelength of λ = 405 nm on a two-layer a-Si / Ag medium from the side of a glass substrate. The formation of the micro relief is studied during direct recording by semiconductor laser pulses with λ = 405 nm on the a-Si layer. Parameters of two-layer structure a-Si / Ag for direct laser recording are optimized.

ABSTRACTThe change with time in the electrical conductivity of a hydrogenated-tritiated amorphous silicon film (a-Si:H:T) has been studied. The conductivity decreased with time after deposition. A model is developed to account for the decrease. The radioactive decay of tritium into helium produces energetic beta particles. Each β particle creates over 1500 electron-hole pairs in the film thereby increasing the conductivity of the film. The 3He atoms diffuse away leaving dangling bonds behind. We find that neutral dangling bonds (D0) are responsible for the decrease in conductivity by acting as recombination centers in the material.
