Doping density and carrier lifetime in PassDop sample. (a) Qualitative doping density, which is significantly increased in the laser-induced doping region (at the upper surface between the green lines) and (b) damage (map of the μPLS intensity) at the edges of the laser affected region which decreases the lifetime (white arrows).
