Electromagnetic
'Swamps' Don't Always Bog Electrons Down
Electrons
tunnel through energy barriers together, even though the environment of the
particles is electrically messy.
DURHAM, NC
- Scientists have designed a simple system to study how electrons travel
through energy barriers instead of over them.
This
unusual behavior, called tunneling, is the particle equivalent of a person
being able to walk through rather than over a mountain. The particle behavior
is also one of the most common signs that everyday physics has broken down and
quantum mechanics now controls the system.
