Resistivity temperature graph
WebApr 12, 2024 · 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 20%. Finally, the high critical temperature values of the films enabled optimal performance at 2.2 K. The improved T c was achieved by applying an RF bias during film growth. WebTables (1, 2 & 3) as well as graphs representing these tables shows that as the temperature rises the value of resistance increases. ... From the results it is noted that the thermal conductivity is very sensitive for temperature and the resistivity of the three copper wires increased with the increasing of temperature. References [1].
