Fig. 3: Connection topology of PNRs and the matrix.
From: Harnessing local inhomogeneity for enhanced dielectric energy storage
a PNRs with different aspect ratios. From top to bottom are morphology, P–E loops and energy storage parameters. The color marks polarization (P). b PNRs with a 32:2 aspect ratio rotate from parallel (0.0 deg) to vertical (90.0 deg) to the electric field. c PNRs with plate, fiber and sphere shapes either vertical (v) or parallel (p) to the electric field. The electric field is along y direction.
