摘要：

The charge of quasi-particles in the fractional quantum Hall regime was determined via quantum shot noise measurements. The noise is generated by a current flow through a partially transmitting quantum point contact in a two dimensional electron gas and is directly proportional to the charge of the quasi-particles. We measured quantum shot noise at a filling factor of 1/3 and found that the charge of the quasi-particles is e/3 as predicted by Laughlin. (C) 1998 Elsevier Science B.V. All rights reserved.
