Humberto Cabrera

Some researchers reported ns, others ps, there is mismatching in literature. Which are more reliable values, if somebody measured?

Jorge Martín Meichtry

Dear Humberto, we´ve measured charge carriers lifetime in pure P25 using Time Resolved Microwave Conductivity, and we observed that lifetime extended up to the microsecond range, although that depends also on the presence of adsorbed species; see the manuscript attached.

Best regards

Dear Jorge, thanks for the information and the manuscript

best regards
