universal conductance fluctuations

[¦yü·nə¦vər·səl kən′dək·təns ‚flək·chə‚wā·shənz] (electronics) Fluctuations in the conductance of a quantum wire, as a function of applied voltage, whose root-mean-square value depends only on the geometry of the device, and which are reproducible in any one sample but vary in detail from one sample to another.
