Abstract

Resonant tunnelling through two impurities has been observed in a vertical double-barrier GaAs/AlGaAs tunnelling diode. It manifests itself as a peak in the I-V characteristic near the conductance threshold. Analysis of the position of the current peak, its shape and the shift in magnetic field parallel to the current provides information about the characteristics of the two impurities.

Abstract

Contrary to some recent observations of a gradual increase of 1/f -noise with decreasing carrier density in a 2DEG in Si and a 2DHG in GaAs, we have observed a non-monotonic variation of noise power in a 2DEG in Si. We discuss the role of the following effects in the noise near the carrier density where ∂R /∂T changes its sign: i) formation of an electron glass; ii) percolation transition; iii) existence of a narrow impurity band at the Si-SiO2 interface. We also analyse the effect of temperature fluctuations in the observed non-monotonic behaviour of the noise power. (© 2006 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
