Abstract

We study low frequency noise and noise correlation in two kinds of mesoscopic conductors to investigate the contribution of Fermi statistics in coherent electron transport. In Y-shaped triple quantum point contact structures, we observe multi-level switching noise which is much bigger than the expected contribution due to Fermi statistics. In a second device structure, a partially transmitting surface gate is used to split ballistic electrons injected from a quantum point contact. In our noise measurements on these second kind of structures, within the resolution of our noise measurement setup (10-20 V2/Hz), no excess noise correlation between the reflection and transmission voltages is observed.
