“…Otherwise the increase of the particle size to10.6 nm the conductivity value decreases as a result of increasing of the particle size. These results are compatible with the assumption of the ''core-shell'' model [31] of the nanosized grains in the materials under study. According to this model a grain consists of an inner fully crystalline ''core'' and an outer highly disordered, defective and non-stoichiometric ''shell''.…”

Air-stable CdZnTe nanostructure thin films were synthesized by inert gas condensation technique under constant preparation conditions of Argon gas flow, deposition rate and substrate temperature 300 K. The CdZnTe nanostructure thin films were deposited on freshly cleaned glass substrates. The film thickness has been raised from 20 to 70 nm. The films exhibited nanocrystalline single phase cubic structure as indicated by grazing incident in-plane X-ray diffraction patterns and ensured by HRTEM diffraction patterns. The average particle size of examined films was increased from 5.6 to 10.6 nm by raising thin film thickness as determined from HRTEM images. The average particle size of examined film was measured by HRTEM after 230 day aging and shows a relative stability in the particle size. The optical transmission, reflection and absorption spectra were influenced by the increasing of the particle size P s . The optical band gap E g decreased from 3.24 to 3.05 eV as average particle size enlarged from 5.6 to 10.6 nm. Higher values of absorption coefficient spectra and refractive indices have been observed for films of higher particle size. Relative stability of optical properties has been detected for aged film. The d.c. electrical conductivity behavior at different temperatures was tuned by changing the particle size of examined nanocrystalline films. The activation energy values are in the range 0.67-0.77 eV regardless the change in particle size.

“…The precipitation of nanoparticles within the glassy matrix can thus either enhance or reduce the conductivity. To tailor the properties of these nanocomposites and to make them suitable for practical application, the understanding of their microsructural aspect is foremost important [14,15].…”
