Inverse barocaloric effects in ferroelectric BaTiO3 ceramics

Periodic Slab LAPW Computations for Ferroelectric BaTiO3

Linearized augmented plane wave (LAPW) calculations are performed for periodic (001) and (111) slabs of BaTiO3 to understand the effects of surfaces on ferroelectric BaTiO3. The (111) slab is found to be much less stable than the (001) slab. The average surface energies are respectively 3700 erg/cm and 1600 erg/cm. The depolarization field is sufficiently large in the ideal unrelaxated slab to ...

Integrated Ultrafast Nonlinear Optical Devices in Silicon

Silicon-on-insulator (SOI) provides an intriguing system for developing massively integrated optics. By leveraging the processes and systems developed for electronics fabrication, it is possible to make highly repeatable devices where complexity can be scaled up through the use of wafer-scale batch fabrication. Because the mode concentration in silicon waveguides is two orders of magnitude high...
