Extended Data Fig. 3: Basic characterization of the spin-LED.
From: Room-temperature spin injection across a chiral perovskite/III–V interface
a, EL spectra (not polarized) with increasing applied current. b, EL intensity versus applied current showing linear increase. I–V curves of the LEDs in dark and under illumination: the LED with no (R/S-MBA)2PbI4 present (c,d) and the full LED stack including (R/S-MBA)2PbI4 (e,f).
