Abstract

The study of structural and electrical properties of self-assembled ZnO nanoparticles in polystyrene-acrylic acid, [PS]_m/[PAA]_n, diblock copolymer on p-type (100) Si substrates is reported. The particles were developed in [PS]_m/[PAA]_n with four different block repeat spherical nanodomains is used to template the ZnO nanoparticles onto the substrates. Our methodology for the ZnO nanoparticle synthesis involves incorporating the ZnCl₂ precursor in the copolymer in liquid phase, spincasting the doped solution on the substrate and, then converting the precursor into ZnO. Room temperature I-V characteristics of the ZnO nanocomposite film on p-type (100) Si, measured for the first time, exhibited rectifying junction properties with an ideality factor n=1.7, and the transport mechanism in this system was evaluated from the electrical studies and discussed
