Growth Evolution of Polycrystalline CdTe/CdS with Atomic Scale Resolution via Molecular Dynamics

A new method to study polycrystalline growth of CdTe layers has been developed using Molecular Dynamics (MD). The results show the creation of polycrystalline CdTe/CdS structures that closely recreate the morphology of experimental polycrystalline growth. The growth shows the nucleation and coalescence of grains at early stages for CdS on amorphous CdS and CdTe on polycrystalline CdS.
