When molybdenum disulfide is grown over substrate(hBN) by cvd technique, there is van der waals force between molybdenum disulfide and hBN. Molybdenum disulfide finds the most stable position over hBN. For this, MoS2 cluster rotates over the substrate. Rotation angle is 0 & 60 degree over the substrate.
How to rotate the MoS2 cluster (considering unit cell or center of mass of MoS2 or something else) over substrate in computer simulation?
