The attempt is made to decrease transition resistance of ohmic contacts to high-ohmic semiconductors (such as cadmium telluride and semi-insulating gallium arsenide) due to extra free carrier concentration creating in near-contact region by optical stimulation. Various tested construction variants of such contacts are presented in this paper. The illumination is shown to be useful for drastic (several orders of magnitude) decreasing of two-polar sample total resistance. This result may be interpreted only as transition resistance decreasing upon contact illumination.

Abstract—It is shown that illumination of ohmic contacts to highresistance cadmium telluride and gallium arsenide samples affects not only the transient resistance of the contact, but the bulk conductivity of samples by increasing the concentration of free charge carriers. The model explaining the increase in the volume con ductivity of the sample under the illumination ...

A method of separate determination of two-pole sample volume resistance and contact resistance is suggested. The method is applicable to high-ohmic semiconductor samples: semi-insulating gallium arsenide, detector cadmium-zinc telluride (CZT), etc. The method is based on near-contact region illumination by monochromatic radiation of variable intensity from light emitting diodes with quantum energies exceeding the band ...

Photoconductivity has been thoroughly studied for a long time. However, most researchers have examined
photoconductivity of semiconductors while illuminating the entire surface of samples. The present paper
examines the effect of local exposure that ensures a high level of injection of free charge carriers upon the
conductivity of high-ohmic cadmium telluride and semi-insulating gallium arsenide samples and upon ...

The influence of light illumination of ohmic contacts to high-ohmic gallium arsenide and cadmium telluride samples is investigated. It is revealed, that near-contact –area illumination influences not only upon transition resistance, but also upon volume conductivity of the samples due to increasing of free carrier concentration. The new method of separate determination of ohmic contact ...

Exploring life cycles of fungi is insightful for understanding their basic biology and can highlight their ecology. Here, we dissected the sexual and asexual life cycles of the obligate alkalophilic ascomycete Sodiomyces alkalinus that thrives at extremely high pH of soda lakes. Sodiomyces alkalinus develops acremonium-type asexual sporulation, commonly found in ascomycetous fungi. However, the ...

The framework of simple opposition realism - anti-realism is not enough to analyze the views on the reality of unobservable objects of quantum theory. First, it is necessary to distinguish between realism in relation to the theory and realism in relation to the theory’s objects. Secondly, realism in relation to classical objects can be combined, ...

In this short review, we first discuss the results, which are mainly devoted to the generalizations of the famous Kohn–Luttinger mechanism of superconductivity in purely repulsive fermion systems at low electron densities. In the context of repulsive-U Hubbard model and Shubin–Vonsovsky model we consider briefly the superconducting phase diagrams and the symmetries of the order parameter ...
