Transient Charging Dynamics in Stacked Ga2O3/ZnO Photovoltaic Units Governing Wavelength‐Selective Polarity Switching

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work reveals a “Photovoltaic‐Capacitance” coupling mechanism in stacked Ga2O3/ZnO devices, defining the ZnO/graphene interface as a novel Photovoltaic Dynamic‐Capacitor (PDC). The wavelength‐selective bipolar response enables a physical layer secure communication protocol based on ternary optical logic (“1,” “0,” “−1”).
