This work shows an oxide‐based phototransistor that senses visible light by creating highly defective interfaces (HDIs). HDIs are fabricated by using nanowires of hafnium oxide (HfO 2 ) and titanium dioxide (TiO 2 ) embedded in indium gallium zinc oxide (IGZO). It sensed red light with photo responsivity of 178.7 A/W and a signal‐to‐noise ratio of 10 5 .
