The effect of electrodes plays a vital role in the construction of nano electronic devices. Two different electrodes are constructed with gold and platinum atoms and are attached with NiO nano wire in order to study the effect of electronic transport properties. In addition, in the NiO device N and Fe atoms are substituted and their electronic transport properties are also studied. From the observed results it is evident that the gold electrode NiO nano devices show better performance than that of the platinum electrode connected NiO nano device. The transmission and PDOS spectra show that in the gold electrode NiO devices N doped NiO nano device gives better performance than the other two. In the case of platinum connected NiO nano devices, Fe doped NiO nano device gives better performance than the other two.
