Abstract

Infrared quenched persistent photoconductivity (PPC) is studied as a function of wavelength and photon dose in order to investigate a defect structure which may be responsible for PPC in YBa2Cu3O6+x. It is found that the magnitude of IR quenching saturates quickly as function of visible photon dose, long before the PPC effect saturates. The wavelength dependence is essentially linear below 1.3 eV and saturates above. The photon dose dependence of IR quenching indicates behavior which cannot be explained using a purely oxygen ordering model for PPC. © 1999 The American Physical Society.
