Quantum-interference origin and magnitude of 1/$f$ noise in Dirac nodal line IrO${}_2$ nanowires at low temperatures

Po-Yu Chien, Chih-Yuan Wu, Ruey-Tay Wang +4

We present 1/$f$ noise measurements of IrO${}_2$ nanowires from 1.7 to 350 K. Results reveal that the noise magnitude (represented by Hooge parameter $\gamma$) increases at low temperatur…
