electron tunneling

synonym: electron quantum tunneling
https://doi.org/10.1351/goldbook.08806
Quantum mechanical effect of passing an electron through a potential energy barrier separating two energy equivalent regions.
Note:
The electron tunneling effect is exploited, e.g., in scanning tunneling microscopes, pressure sensors based on quantum tunneling polymer composites and in touchable panels of electronic devices.
