"transformed existing commercial LED to also control interconversion electron spin at room temperature, increasing data processing speeds, decreasing power needs... chirality controls spin by creating filter blocking electrons spinning in wrong direction... chiral perovskites lets LED emit polarized light at room temperature without magnetic field... degree of polarization boosted to about 15%, a direct measure of spin accumulation in the LED... LEDs, solar cells, telecommunication lasers"
