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 of the contact region is presented. The procedure for separate determination of the transient resistances of the ohmic contact and the sample volume, suitable for high resistance semiconductors, is proposed.

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 ...

The phenomenon of photoconductivity has long been well studied. However, in the overwhelming majority of studies, the photoconductivity of semiconductors was studied by illuminating the entire surface of the samples. In this paper we investigated the effect of local illumination, which ensures a high level of injection of free charge carriers on the conductivity of ...

The influence of the illumination of the n-type semi-insulating gallium ar-senide sample central part upon the sample conductivity has been investigated. The luxe-ampere dependence beginning from some light intensity has been shown to become linear, and its angular coefficient increased with illuminated area diameter increasing. This dependence has been described by the degree function between ...

The method of separate determination of two-pole sample volume resistance and contact resistance is suggested. The method described is applicable to high-ohmic semiconductor samples: semiinsulating 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 energy exceeding band ...

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 ...

The effect of local illumination providing a high level of freecarrier injection on the conductivity of a sample of semiinsulating cadmium telluride and on the properties of ohmic contacts to the sample is studied. It is found that, irrespective of the illumination region, the contact resistance of ohmic contacts decreases and the concentration of majority ...

We report about a study of the formation and current transport mechanism of ohmic contacts to n+-InN with electron concentrations of 2×1018, 8×1018, and 4×1019 cm−3. Pd/Ti/Au ohmic contacts are formed by the proposed approach of simultaneous magnetron metal deposition and in-situ temperature annealing, which allows obtaining a low contact resistivity (4.20±2.67)×10−6 Ohm· cm2. The additional rapid ...

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, ...

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 ...
