Minority charge carrier lifetime mapping for different Si samples. The schematic diagram of minority charge carrier lifetime: a the measurement instruction and b the mechanism of carrier lifetime measurement: the photoconductivity, which is closely related to the carrier concentration, is measured by microwave absorption during and after the excitation with a rectangular laser pulse. c Si NW without TMAH treatment; Si NW with TMAH treatment for d 50, e 60, and f 70 s.
