Electron Tunneling Times

Superoscillations and tunneling times

It is proposed that superoscillations play an important role in the interferences that give rise to superluminal effects. To exemplify that, we consider a toy model that a wave packet to travel in zero time and negligible distortion, a distance arbitrarily larger than the width of the wave packet. The peak is shown to result from a superoscillatory superposition at the tail. Similar reasoning a...

Tunneling times and “ Superluminal ” Tunneling : a Brief Review

In the First Part of this paper [that was submitted for pub. in 1991 and appeared in print in Phys. Reports 214 (1992) 339] we critically review and analyse the main theoretical definitions and calculations of the sub-barrier tunnelling and reflection times. Moreover, we propose a new definition of such durations, on the basis of a recent general formalism of ours (already tested for other type...

Indirect Electron Tunneling

Indirect electron tunneling is observed in germanium diodes by detecting small perturbations in their I-V characteristics at low temperatures that occur when the applied potential equals the energy of emitted phonons. Frequencies of the observed phonons are calculated to a comparable degree of accuracy (±0.3E12 Hz) with neutron scattering data. Electronic differentiation, used to closely inspec...

Single Electron Tunneling Junctions

This paper and its associated Python programs explore the dynamics of single electron tunneling junction (SETJ) circuits. SETJs can potentially be used as nonlinear circuit elements to implement new paradigms for information processing. I show that an isolated SETJ circuit with a constant bias voltage and sinusoidal pump offset can produce a variety of interesting nonlinear behavior. By adjusti...
