Abstract

Transient laser‐induced electrical signals with peak voltages of ∼50 mV and 2Cu₃O_7−x in the absence of an applied current. It is demonstrated that the signal polarity is reversed when the films are illuminated through the substrate rather than at the air/film interface. The mechanism for this effect has yet to be elucidated.
