Extended Data Fig. 4: Validating terahertz near-fields on GaAs(110).
a–c, QTHz–ESF,pk curves (left) and THz-CC waveforms (right) for the same tip positions as in Fig. 3. The measurements were all acquired at Vd.c. = 1.2 V and Id.c. = 100 pA, while the waveforms were acquired at ESF,pk = 170 V/cm (a), ESF,pk = 110 V/cm (b), and ESF,pk = 40 V/cm (c). The y-axis in c is shown in reverse due to an inverted phase for the terahertz pulse waveform over the resonator defect.
