Abstract
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.
