Research Abstract

The Id-Vg characteristics of an amorphous alloy FET were measured in nonmagnetic and magnetic fields at room temperature. The transistor reveals one-electron Coulomb oscillation with period of 0.28 mV, Fabry-Perot interference with period of 2.35 E-6 V in nonmagnetic field, and Fano effect with period of 0.26 mV for Vg and 0.2 T for magnetic field. Since the gap energy is 265 times larger than thermal energy (25.6 meV) at room temperature, this intriguing phenomenon does not violate an essential principle. NMR, positron annihilation spectroscopy and neutron scattering studies show that H occupation between Ni atoms of neighboring icosahedral clusters provides a distinct model of quantum dot tunneling. From standard MD calculation, we construct a local structural model for amorphous alloys. These phenomena could be excluded by charge density waves that the low-dimensional component of clusters, in which the atoms are lined up in chains along the [130] direction.
