title = "1 ƒ noise in copper whiskers",
abstract = "We have observed current-induced 1 f{hook} noise in thin copper crystals ({"}whiskers{"}) ranging from 0.15 to 1.20 cm in length. We find that the noise power is proportional to the square of the applied d.c. voltage and has a power spectrum varying approximately as f{hook}-1 over the frequency range 0.5 Hz-2 kHz. The magnitude of the noise is 102-103 times larger than typical magnitudes reported for copper films of similar volume.",

note = "Funding Information: which agrees in approximate magnitude with measurements on a number of metals. It has been suggested2{\textquoteright}5 that the current-induced noise in metal films is generated by energy fluctuation in the sample which is weakly connected with a thermal reservoir at temperature T. Such fluctuations must of course depend strongly on the thermal boundary conditions and hence the role of the substrate in both the * work supported by NSF under contract NSF-DMR7S-14360 and by the Louis B.
