Abstract

Electric-current-induced voltage oscillation at 600-740 kHz was observed in the current-voltage curves of nanoscopic size tunnel junctions arranged in a low-capacitance, multiple-junction configuration of ((Ni60Nb 40)100-xZrx)100-y Dy (x=30, 35, 40 and 45, 9.1≤y≤14.8) glassy alloys in the temperature range of 373 K to 6 K. This behavior appeared to be derived from Coulomb oscillation resulting from the tunneling of individual deuteron charging and discharging the vacancy capacitance of Zr-D-□-D-Zr atomic bond arrays among Zr-tetrahedral clusters, where □ is the vacancy barrier between clusters.
