Low-E Glazing Performance by Seed Structure Optimization

摘要

A bi-layer seed layer can exhibit good seed property for an infrared reflective layer, together with improved thermal stability. The bi-layer seed layer can include a thin zinc oxide layer having a desired crystallographic orientation for a silver infrared reflective layer disposed on a bottom layer having a desired thermal stability. The thermal stable layer can include aluminum, magnesium, or bismuth doped tin oxide (AlSnO, MgSnO, or BiSnO), which can have better thermal stability than zinc oxide but poorer lattice matching for serving as a seed layer template for silver (111).
