Electronic Conductance of Nano Composite Polymer Single Walled Nanotube with Spin Spray Varian

Abstract

We have studied electronic conductance of nano composite polymer single wallednanotube with spin spray variant by using layer by layer technique. The study showedthat there existed a critical number of polyelectrolyte bilayer below which the electronicconductance of the material was negligible. The sheet conductance increased above thecritical value. This indicated that the material conductivity was controlled by theformation of a percolating network of highly conducting nanotubes in an insulatingpolymetric matrix. We have presented the dependence of junction resistance on thelayer separation leaded to the logarithmic behavior. The quasi two dimensional modeltreated the nanotube as infinitely conducting rods with resistive junctions. A junctionwas formed when projections of two nanotubes on the plane of the material intersect.The junction resistance increased with inter layer separation. The results found werecompared with previous results and were found in good agreemen
