Fowler-Nordheim Tunnelling Principle

Post Posted: Jul 10, 09 12:49

Fowler-Nordheim Tunnelling Principle

The floating gate can be charged and discharged by using Fowler-Nordheim "tunnelling". A principle whereby certain electrons subjected to an electric field can cross the forbidden gap of an insulator to enter the conduction band and thus flow freely for a short distance to a positively charged area.

Is this 'tunnelling' principle still used today for flash memory chips in SIM Cards, mobile telephones and memory expansion cards?
