Extended Data Fig. 7: The comparative trial between light-emitting diodes (LEDs) with and without the trilayer construction.
From: Topology-induced chiral photon emission from a large-scale meron lattice
The spin polarization of spin injector was contributed by the spin selectivity from topological meron lattice, since the trilayer had a neglectable out-of-plane magnetic remanence. a, The circularly-polarized electroluminescence (EL) spectra of the topology-induced light-emitting diode (T-LED) with meron lattice construction. b, The circularly-polarized EL spectra of the LED without Fe film, which was placed in a 9 T magnetic field for 2 hours before the deposition of the Pd electrode.
