Resistivity of a wire graph
WebApr 12, 2024 · The high sheet resistance was attributed not only to the small thickness of the film but its high resistivity (6.25 μ Ω m) in comparison to the typical values acquired for NbN. The high resistivity was obtained by using a nitrogen-rich gas mixture during sputtering, with N 2 % = 27.3 % in this work as compared to the previously used value of … WebThese results show that as the length of the wire increases, the resistance increases, as well. Furthermore, if you double the length of the wire, the resistance is roughly doubled. …
