| Abstract Scope |
Te-particles that form during the growth of CdZnTe (CZT) single crystals are a macroscopic defect with apparent origin in the CZT melt. As the freezing point for CdTe is 1365 K and that of Te is 722 K it is important to understand the mechanisms by which presumably l-Te(Cd)-particles form within the CZT solid. A new interatomic potential (IAP) for Te has been developed based on a modified Stillinger-Weber form as was done previously for Se by others in order to study large systems more suited to crystal growth modeling. The IAP is used to study Te melting and the Te melting line via molecular dynamics. Results for density changes, enthalpy of melting, and Te liquid structures will be presented and compared to ab initio and literature results. The use of the new IAP for Te in developing an improved IAP for CdTe is discussed. |
