A critical review on polyvinylidene fluoride (PVDF)/zinc oxide (ZnO)-based piezoelectric and triboelectric nanogenerators

JPhys Energy
In this current energy crisis era, piezoelectric and triboelectric effects are emerging as promising technologies for energy harvesting. Polyvinylidene fluoride (PVDF) and its copolymers are well-known piezoelectric materials with high piezoelectric ...

Distinct origins of electric-field-axis and polarization-axis asymmetries in ferroelectric hysteresis

Materials & Design
Ferroelectric hysteresis asymmetry critically influences switching stability, imprint, and preferential polarization states in nonvolatile electronic devices. However, hysteresis asymmetry is generally characterized only by horizontal loop shifts, partly

Ultrahigh pyroelectricity in monoelemental 2D tellurium [PDF]

We report an ultrahigh pyroelectric response in van der Waals bonded layers of two-dimensional (2D) tellurium (Te) nanosheets (thickness, d = 4 to 5 nm) at periodic on-off temperature oscillations. For the first time a large pyroelectric coefficient, Pc ~
