WebMar 1, 2024 · Here, we observe in the example of an Fe-doped LiNbO 3 bulk single crystal the existence of a purely intrinsic “piezophotovoltaic” effect that leads to a linear increase in photovoltaic current density. The increase reaches 75% under a low uniaxial compressive stress of 10 MPa, corresponding to a strain of only 0.005%. WebFeb 7, 2011 · Abstract. A substantial increase in photoferroelectric image storage sensitivity has been achieved in ferroelectric-phase PLZT ceramics by implanting protons (H + ions) into the image storage surfaces. The 10- to 100-fold increase in sensitivity is attributed to increased densities of carrier photoexcitation and trapping centers and to an increase in … WebThis is where the promise of the ferroelectric photovoltaic effect lies (photoferroelectrics). Currently, the state of the art in photoferroelectrics shows that a high open circuit photovoltage is achievable through the use of epitaxial bismuth ferrite (BFO) thin films.
