At this interface, a high fixed negative charge density, Q(f), is present after annealing which contributes to ultralow surface recombination velocities similar to 5 nm), the polarity of the effective charge density changed from negative to positive. The observed changes in Q(f) and the associated field-effect passivation had a significant influence on the injection-level-dependent minority carrier lifetime of Si.
