By Paata J. Kervalishvili, Panayotis H. Yannakopoulos

This number of chosen overview papers specializes in issues similar to electronic radiation sensors and nanosensory platforms for nanotechnology purposes and built-in X-ray/PET/CT detectors; nanophosphors and nanocrystal quantum dots as X-ray radiation sensors; the luminescence potency of CdSe/ZnS QD and UV-induced luminescence potency distribution; investigations dedicated to the quantum and multi-parametrical nature of failures and the modeling thereof utilizing quantum seek and quantum question algorithms; sum-frequency-generation, IR fourier and raman spectroscopy tools; in addition to investigations into the vibrational modes of viruses and different pathogenic microorganisms geared toward developing optical biosensory platforms. this can be through a evaluation of radiation resistant semiconductor sensors and magnetic size instrumentation for magnetic diagnostics of high-tech fission and fusion set-ups and accelerators; the assessment of using neutron-radiation, 10B-enriched semiconducting fabrics as thin-film, hugely trustworthy, hugely delicate and fast-acting powerful solid-state digital neutron-detectors; and the irradiation of n-Si crystals with protons, which converts the “metallic” inclusions to “dielectric” ones in isochronous annealing, as a result resulting in opto/micro/nanoelectronic units, together with nuclear radiation nanosensors.

The booklet concludes with a comparative research of the nitride and sulfide chemisorbed layers; a chemical version that describes the formation of such layers in hydrazine-sulfide and water sodium sulfide answer; and up to date advancements within the microwave-enhanced processing and microwave-assisted synthesis of nanoparticles and nanomaterials utilizing Mn(OH)2.

Ohmic contacts needed in the Hall-measurements were made by rubbing aluminum on the samples surfaces. Characteristics nH À T, μH À T and σ ÀT were mapped from the nitrogen boiling point up to room temperature, 77– 300 K, with relative errors less than ~10 %.

The irradiated crystals were subjected to IA in the temperature range 80–600  С with step of 10  С for 10 min. The changes in the character of electrons Hall-concentration nΗ, Hall mobility μΗ and material conductivity σ dependences on temperature T were studied in specimens treated at annealing temperatures Tann from the range 80– 600  С. Hall-measurements were performed not only in the dark, but also under the infrared (IR) illumination (photo-Hall-effect). 44 eV which correspond, respectively, the ionization energies of A-and E-centers – vacancy complexes with oxygen and phosphorus, the dominant electron-levels in irradiated silicon.
