Description
Summary:Herein, we fabricate pol [2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene] (MEH:PPV) and Silver (Ag) decorated multiwall carbon nanotubes (MWCNTs) composite based device by spin coating technique. The MWCNTs have been decorated with silver nanoparticles (NPs) via silver nitrate solution. Field emission scanning electron microscope (FESEM) results are in favor of the required conformation of Ag NPs on to the side walls of MWCNTs. The presence of Ag NPs in the composite has also been verified through X-Ray diffraction (XRD). The electrical properties of MEH:PPV/AgMWCNTs composite based devices have been analyzed to determine the various important diode parameters and to explain the charge transport mechanism in the device. The charge transport mechanism is explained by double logarithmic I-V curve, which show two distinct mechanisms: Ohmic conduction at low voltage and trap limited space charge conduction (TCLC) at large applied voltages.
