Root-mean-square conductance fluctuation magnitude δGrmsas function of temperature for NW1 and NW2 devices. The dot-dashed, dashed, and dotted curves are the theoretical predictions of Equation 1 with the exponent of temperature p = 2, 3, and 4, respectively, for the electron-phonon relaxation rate 1/τep = AepTp. The inset shows the extracted electron dephasing length Lφ as a function of temperature for the two nanowires. The dashed curve indicates a T3 temperature dependence. The data points at 10 K could be subject to large uncertainties and are only drawn for reference.
