SpinLED

spinLED is a research project focused on the development of advanced light-emitting diodes (LEDs) that utilize the spin of electrons to influence their light emission properties. Traditional LEDs generate light by passing an electric current through a semiconductor material, causing electrons to recombine with holes and release photons. SpinLED aims to enhance this process by controlling the spin polarization of the injected electrons.

The core idea behind spinLED is to inject spin-polarized electrons into the semiconductor. The spin of an electron refers to its intrinsic angular momentum, which can be oriented in one of two directions, often referred to as "spin-up" and "spin-down." By ensuring that the injected electrons have a preferred spin orientation, the researchers aim to influence the polarization of the emitted light. This could lead to LEDs that emit circularly polarized light, a property that is not easily achieved with conventional LED technology.

Potential applications for spinLED technology include improved displays, where circularly polarized light could enhance 3D viewing experiences without the need for passive glasses. It also holds promise for optical communication systems, where spin-polarized light could be used for higher bandwidth data transmission. Furthermore, the ability to control light polarization at the emitter level could open new avenues in sensing and quantum information processing. The research is ongoing, with efforts focused on achieving high spin injection efficiency and maintaining spin polarization throughout the device operation.
