A non-vacuum process for preparing nanocrystalline CuIn_1−xGa_xSe₂ 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...

Psychophysical Measures of Two-tone Suppression and Distortion Products (2f₁-f₂) and (f₂-f₁)

Psychophysical two-tone suppression and the growth of the (2f• --f2} and • --f•) distortion products were measured in four normal-hearing young adults using a forward-masking paradigm. The stimulus parameters investigated were: (1)f• = 750 and 3000 Hz; (2)f2/f• = 1.1 l, 1.26, and 1.41; (3) L• = 50, 65, 80, and 90 dB SPL; and (4) L2 -L• varied from -20 to + 20 dB in 10-dB increments. It appears ...

Photovoltaic Devices Employing Ternary PbS_{<italic>x</italic>}Se_{1<italic>-x</italic>} 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...
