Abstract Both Sb-doped Germanium and Ge-Si solid solution single crystals with resistivity from 1.5 to 7 Ω·cm were grown using the Czochralski method. The optical transmission of stability their properties studied by infrared Fourier spectroscopy at a wavelength 10.6 μm temperature range 25 60 °C. It was found that decreasing background impurities concentration leads reduction absorption room while not affecting thermal properties. Thermal germanium increases adding 0.2 0.8 % silicon.

Oxygen impurities and optical properties of Sb-doped germanium single crystals were investigated with Fourier transformed infrared spectrometry. The effect oxygen on crystal structure was shown. effects annealing in the temperature range 623–723 K behavior dissolved have been investigated. It found that at lower partial pressure leads to formation thermal donors (TD) basis atoms. established TD decrease unbound concentration is accompanied by increase stability crystals.

Introduction .

The traditional process of sorting and selecting information has changed dramatically under the influence technology. Influencers have become new authorities. Until recently, creation an influencer proceeded according to classical scheme: idol - expertise norm reward/punishment authority. However, CGI technologies created a phenomenon digital influencers. influencers engage user's imagination inspire awe (AWW Inc.). source influencer's power is their ability utilize media literacy. are...

This paper considers the possibility of implementing an automated information system at enterprise, to manage distribution energy. Also considered are problems that will be aimed solving implementation AIS this type, as well established requirements for developed system, functional and proposed some schemes options use which should ensure optimal electricity in production.

AbstractHomogeneous Sb-doped single crystals of Ge–Si solid solutions are grown with a silicon content 0.2 to 0.8 at %. The optical absorption resistivity (2–3) Ω cm is studied by IR Fourier spectroscopy wavelength 10.6 μm in the temperature range from 25 60°C. It found that introduction into antimony-doped germanium improves stability properties crystals.
