Abstract

On page OP49, M.-H. Jo and co-workers describe a method of control over photocurrent detection by manipulating ferroelectric domain configurations. The magnitude is spectrally centered around charged domain walls that are associated with oxygen vacancy migration in BiFeO3, where potential gradients caused by spontaneous polarization yield asymmetric and nonlinear photocarrier dynamics.
