Chiral Induced Spin Selectivity Enabling a Room Temperature Spin Polarized Light Emitting Diode

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.
