Extended Data Fig. 4: CEP dependence for HHG in the TSS.
From: Tunable non-integer high-harmonic generation in a topological insulator
HH intensity, IHH, generated in the TSS as a function of the CEP, φCEP, along the black dotted line in the inset. The intensity of the emitted HHs monotonically increases with increasing φCEP.
