Electrical properties of polymer light emitting diode using polyaniline-۵% SiO۲ nanocomposite as efficient hole-injection layer

چکیده مقاله

Polyaniline-5% Fumed silica (PANI-5% SiO2) nanocomposite has been prepared to use as hole-injection layer in polymer light emitting diode (PLED) with structure ITO/PANI-5% SiO2/MEH-PPV/Al. The current densityvoltage (J-V) characteristic of the PLED has been investigated. The Fowler-Nordheim tunneling model has been used to explain the obtained J-V data and the logarithmic plot of the J-V characteristic of the fabricated device showed a power law behavior (J∝ Vk+1) with two distinct regions.
