    Abstract

    Spun films of novel substituted lead phthalocyanine derivatives between aluminum and indium tin oxide electrodes exhibit large, reproducible negative differential resistance (NDR) in their current–voltage characteristics and can be electrically switched between a high conductance on state and a low conductance off state. Space charge limited conduction mechanism was identified from temperature dependent measurements to be responsible for charge transport. The NDR effect may be due to the charge storage in the structure near the electrodes.
