Extended Data Fig. 3: Time-domain THz signal and corresponding spectrum.
From: Terahertz parametric amplification as a reporter of exciton condensate dynamics
a, Reflected time-domain signal (TDS) from a gold mirror (reference), a 300 μm-thick 〈110〉 GaP was used to detect the signal. b, The corresponding normalized spectrum showing a broadband spectral regime of 0.5–7.5 THz.
