Molecular Dynamics Simulation of Lithium Niobate (image) Carnegie Institution for Science Share Print E-Mail Caption The image shows a molecular dynamics simulation of lithium niobate under a time varying electric field, which changes the sign of the polarization. Red is niobium, green is oxygen, and lithium shows a range of colors for different time steps. The niobium and oxygen are shown only for one time step for clarity. The image shows a small part of the actual simulation.
