shot noise

British  

noun

1. Also called: Schottky noise.  the inherent electronic noise arising in an electric current because of the discontinuous nature of conduction by electrons

Example Sentences

Some prior theoretical studies have suggested that the charge in a strange metal might not be carried by such quasiparticles, and shot noise experiments allowed Natelson, study lead author Liyang Chen, a former student in Natelson's lab, and other Rice and TU Wien co-authors to gather the first direct empirical evidence to test the idea.

From Science Daily

"The shot noise measurement is basically a way of seeing how granular the charge is as it goes through something," Natelson said.

From Science Daily

Shot noise experiments cannot be performed on single macroscopic crystals but, rather, require samples of nanoscopic dimensions.

From Science Daily

"The low shot noise brought about fresh new insights into how the charge-current carriers entwine with the other agents of the quantum criticality that underlies the strange metallicity," said Si, whose group performed calculations that ruled out the quasiparticle picture.

From Science Daily

Published this week in Science, the measurements of quantum charge fluctuations known as "shot noise" provide the first direct evidence that electricity seems to flow through strange metals in an unusual liquidlike form that cannot be readily explained in terms of quantized packets of charge known as quasiparticles.
