a–c Near-field images of the normalized amplitude s(ω) showing moiré patterns in TBG taken at same position with different excitation frequencies. The twisted angle is ~0.05°. d–f Near-field images of the normalized amplitude s(ω) showing different twisted angles of 0.06°, 0.11° and 0.21° at excitation frequency ω = 1560 cm−1. Scale bars are 500 nm.
