Influence of Annealing and Bulk Hydrogenation on Lifetime Limiting Defects in Nitrogen-Doped Floating Zone Silicon

Rougieux, Fiacre; Grant, Nicholas; Barugkin (Qiaoke), Chog; MacDonald, Daniel; murphy, john


A recombination active defect is found in as-grown high-purity floating zone n-type silicon wafers containing grown-in nitrogen. In order to identify the properties of the defect, injection-dependent minority carrier lifetime measurements, secondary ion mass spectroscopy measurements, and photoluminescence lifetime imaging are performed. The lateral recombination center distribution varies greatly in a radially symmetric way, while the nitrogen concentration remains constant. The defect is...[Show more]
