Twisted layers with moiré superlattices attract attention due to the control of electronic states by the twist angle. We fabricated atomically clean, twisted hexagonal boron nitride (hBN) layers using a chemical exfoliation technique. Inverse FFT images reflecting the moíre potential were obtained using TEM. Density functional theory (DFT) calculations revealed that the overlap of atomic positions in each layer plays a key role in determining the periodicity and distribution of the potential.
