Described herein are spin polarized light emitting diodes (LEDs) and methods of making the same. Spin polarization is achieved via chiral induced spin selectivity where, for example, a stereochemically active cation is included in a perovskite to form the conductive layer of an LED device. Advantageously, the devices and methods described herein allow for spin polarization at room temperature and without application of a magnetic field or ferromagnetic contacts, in contrast to other described spin selective LEDs.

Chiral induced spin selectivity enabling a room temperature spin polarized light emitting diode

The present disclosure relates to a composition that includes a first layer having a first molecule that includes a metal and a halogen, a second layer that includes the first molecule, and a third layer that includes a chiral molecule, where the third layer is positioned between the first layer and the second layer, and the first layer, the second layer, and the third layer form a crystalline structure.
