Abstract

The effect of current on Coulomb oscillation in a (Ni0.36 Nb0.24 Zr0.40)90 H10 glassy alloy was carried out under currents of 1 nA, 10 nA, 100 nA, 1 μA, 10 μA, 100 μA, 1 mA, 10 mA, and 100 mA in the temperature range of 300-6 K. The amplitude of the Coulomb oscillation showed maximum values at around 1 μA. The discrete variation of the oscillation can be described as E=2× 10 -4 exp (2.34 N) (r2 =0.993), showing clear quantization of Coulomb oscillation, where E and N are the units of h/2 e2 and step number, respectively. We suggested that this would be associated with nanometer-sized RC circuits in the alloy.
