Using the density functional theory combined with the effective screening medium method, we investigated the energetics and electrostatic properties of twisted bilayer hexagonal boron nitride (hBN). Our calculations demonstrated that the out-of-plane polarization in AB stacking rapidly decreases with increasing the twist angle and vanishes at the 5 degree.
