Fig. 2: Time-resolved measurement of the SAW-driven EL.
From: Single-photon emission from single-electron transport in a SAW-driven lateral light-emitting diode
a A 350 ns-long pulsed RF signal (top, shown at a low frequency for clarity) is applied to the IDT to create a pulsed SAW. The SAW-driven EL signal (bottom) is delayed by roughly 400 ns owing to propagation of the SAW from the IDT to the n-i-p junction. b Averaged SAW-driven EL and the best fit using H(t) (see Supplementary Note 2).
