description: Optoelectrical properties and magnetoresistance of conductive polymer MEH-PPV, PbS quantum dots and MEH-PPV/quantum dots PbS nanocomposite of different mixture ratio samples were investigated. We made sandwich structures from silver powder solution Ag - polymer - ITO, Ag - quantum dots PbS - ITO, Ag - nanocomposite - ITO and lateral structures of Ag - polymer - Ag, Ag - quantum dots PbS - Ag, Ag - nanocomposite - Ag, to measure volt-ampere characteristics of samples. Volt - ampere characteristics were measured in darkness, under illumination in magnetic field with different magnitudes (0 â 400 mT). Effect of negative magnetoresistance was observed in all samples. Also, under illumination, resistance of samples decreases and this decrease depend on the magnitude of the magnetic field. The model which is chosen to explain this effect is hopping-conduction model.
