Abstract

Following the discovery of Coulomb oscillation by the proton tunneling in Ni-Nb- Zr-H glassy alloys, we investigated the temperature-dependent hydrogen effect for dc electric conduction of the (Ni₃₆Nb₂₄Zr ₄₀)_100-xH_x (0≤x≤15.7) glassy alloys. Electric current-induced voltage oscillation at 660 kHz and evidence of the Coulomb staircase of I-V characteristics show Coulomb oscillation in nanoscopic size tunnel junctions arranged in a low-capacitance, based on proton resonance among the multiple-junctions of the glassy alloys in the temperature range of 240 K to 6 K.
