Polarized electrons are electrons in which spins have a "preferred" orientation or are preferentially oriented in a specific direction. The realization of these electrons has notable implications for physics research, as ...
Engineers working to miniaturize optical systems for modern electronics have seen great success when it comes to the most familiar components, the lenses and optical sensors. It's been more challenging to reduce the size ...
