Improving the Quantum Efficiency of GA-Free Type-II Superlattices

Molecular dynamics modeling of epitaxial growth provides insights relating growth processes to the spectral absorption and charge carrier lifetimes of Ga-free Type-II superlattices. Guided by the growth modeling, epitaxial process modifications were implemented that resulted in Type-II superlattices...

More Information
Summary:Molecular dynamics modeling of epitaxial growth provides insights relating growth processes to the spectral absorption and charge carrier lifetimes of Ga-free Type-II superlattices. Guided by the growth modeling, epitaxial process modifications were implemented that resulted in Type-II superlattices with improved spectral and carrier transport characteristics.
