Extended Data Fig. 8

a, Optical microscope image of the electroluminescent HPHT-hBN device TR3 resolved with a  ×100 objective. The device includes scatterers in the form of subwavelength gold disks and etches in the hBN layer that are randomly distributed across the device’s channel. b, Mid-IR spectrum of TR3 under bias (Vds = 13 V, Vg = 0 V) measured via IR-SMS.
