Extended Data Fig. 4: Continued examples of independently fabricated LEDs’ CP-EL with (R-MBA)2PbI4.
From: Room-temperature spin injection across a chiral perovskite/III–V interface
Circularly polarized emission data from (R-MBA)2PbI4 spin injection into AlGaInP (a,c; same LED architecture as the main text; device 1 and device 2 labelled) and the corresponding polarization versus current plots (b,d). Error bars are one standard deviation of five consecutive measurements (n = 5). The source of the variation in the devices can be attributed to the Joule heating, as described in Extended Data Fig. 6.
