چکیده

The influence of the corona discharge on holographic recording and subsequence chemical etching gratings in Cr/As 40 S 60-x Se x thin film structures was investigated. It established that applied positive leads to increase sensitivity during As-S-Se films, as well amplification diffraction efficiency relief-phase diffractive obtaining result consecutive etching. Among investigated films As system, best results application Argon laser irradiation (488 nm) for composition 39 21 . Applied bring more than up two order, about three order respect ordinary recording. Reciprocally reached a relief formed sequent 30%. Keywords: chalcogenide vitreous semiconductors, grating, discharge, efficiency, selective

A non-vacuum process for preparing nanocrystalline CuIn<sub>1−x</sub>Ga<sub>x</sub>Se<sub>2</sub> materials involving an open-air solvothermal reaction

A non-vacuum, two-step process has been used to prepare a series of nanocrystalline CuIn1−xGaxSe2 (x = 0, 0.25, 0.5, 0.75, 1) materials. An open-air solvothermal preparation in triethylenetetramine solvent was followed by annealing at 500 °C in a nitrogen atmosphere for 20 min. All materials have mixed clustered plate, spherical particle, and nanorod morphologies with the smallest particle diam...

Photovoltaic Devices Employing Ternary PbS<sub><italic>x</italic></sub>Se<sub>1<italic>-x</italic></sub> Nanocrystals

We report solar cells based on highly confined nanocrystals of the ternary compound PbSxSe1-x. Crystalline, monodisperse alloyed nanocrystals are obtained using a one-pot, hot injection reaction. Rutherford back scattering and energy-filtered transmission electron microscopy suggest that the S and Se anions are uniformly distributed in the alloy nanoparticles. Photovoltaic devices made using te...
