Electric field–dependent phonon spectrum and heat conduction in ferroelectrics
This article shows experimentally that an external electric field affects the velocity of the longitudinal acoustic phonons (v(LA)), thermal conductivity (κ), and diffusivity (D) in a bulk lead zirconium titanate–based ferroelectric. Phonon conduction dominates κ, and the observations are due to cha...
