ABSTRACT We have studied the characterization of fabrication of silicon nanowires on thermoelectric material. We have presented the thermoelectric enhancement properties of SIC nanowires on graphite electrode.Thermoelectric properties of composite electrode by fabricating SIC nanowires is charecterised by its fig. of merit ZT, which depends upon thermal as well as electric conductivity of metarial. Normally the thermoelectric fig. of merit ZT, remained stuck in the range of 0?116, however experimental studies have shown that the value of ZT can be significant ally improved by incorporating nanowires into a material structure. We have seen that the dynamic behavior of electrodes in furnaces, shows unexpected rupture, so we have studied the fabrication of SIC nanowires, which has enhanced the thermoelectric properties. The capacity of composite anode is approximately 2.7 times greater than the equivalent graphite electrode and the reversible capacity is approx. 1.8 times greater. The reduced size and dimension of the nanowire increases the influence of the surface, leading to a significant modification of the vibrational properties by increasing the surface scattering phonons,which decreases the thermal conductivity and increasing the thermoelectric fig. of merit ZT.SIC nanowire is pursued for its high temp. Application, this model also emphasis on wide-band gap, of sic nanowires, thus need to operate under extreme conditions.
