We present new evidence that the non-volatile negative photoconductivity (NPC) response of the ZrO2 breakdown path can be suppressed or tuned to different levels by repeated application of a positive voltage-bias on the TiN electrode prior to light exposure. A negative voltage-bias does not produce...
