Summary
Field Emission
is the process where electrons are emitted from a material surface due to the presence of a
Strong electric field
, overcoming the
Work function barrier
without the need for
Thermal Energy
. This
Quantum mechanical phenomenon
is crucial in technologies like
Electron microscopes
and
Vacuum electronic devices
, where
Precise control of electron flow
is required.
