a, STM topographic data taken at V = −30 mV and I = 0.1 nA. The inset shows its Fourier transform, in which the red circles mark the 2 × 2 CDW vector peaks. b, Photon-energy-dependent ARPES measurement of FeGe. Electron-like pockets are observed at A points. Inner potential is determined to be 16 eV. Thick red lines mark out in-plane high-symmetry cuts at various photon energies: hν = 69 eV corresponds to kz = 0 (Γ-K-M); hν = 47 eV and 102 eV correspond to the kz = π plane (A-H-L). Measurement is performed at 8 K.
