electron tunneling

electron tunneling

[i′lek‚trän ′tən·əl·iŋ]
(quantum mechanics)
The passage of electrons through a potential barrier which they would not be able to cross according to classical mechanics, such as a thin insulating barrier between two superconductors.

Other view also relates to the porous nature of electrode which explain how electron-hop was achieved when more porous nature structure was obtained as it provide more efficient electron tunneling system.
They do so by using a scanning electron tunneling microscope.
Electron tunneling effect is of significance in understanding the conductivity of conducting composites by integration an insulator polymer with conductive fillers [23-25].
Examples include electron tunneling, the electrocaloric effect, and the thermoelastic effect.
Elaborating on the results of this study, she said:" We observed that the energy required for the electron tunneling among copper nanoparticles depends on the near infrared absorption peak and these, both, change with respect to layers copper content.
According to the researchers, high-speed signal mixing is made possible by the nonlinear coupling of the internal optical field to the base electron-hole recombination, minority carrier emitter-to-collector transport, and the base-to-collector electron tunneling at the collector junction.
To do so, it exploits the quantum phenomenon of electron tunneling, in which electrons pass through seemingly impenetrable barriers.
