Ferroelectric materials, in addition to possessing the unique property of a reversible,
spontaneous polarization, exhibit a range of other significant and useful properties. These …

The theory and the experimental characteristics of the bulk photovoltaic effect in ferroelectric
and piezoelectric crystals first observed at the Institute of Crystallography have been …

Optical absorption in pyroelectric crystals is accompanied by electrical effects (in addition to
the well-known pyroelectric effect) which are not present in other materials. Optical excitation …

Ferroelectric materials are characterized by a spontaneous polarization that occurs below
the Curie temperature and can be switched using an external electric field. It is well-known …

Ferroelectrics carry a switchable spontaneous electric polarization. This polarization is
usually coupled to strain, making ferroelectrics good piezoelectrics. When coupled to …

A theory is presented for the intrinisic anomalous bulk photovoltaic effect observed in
noncentrosymmetric crystals, eg, BaTi O 3. An exact formula is derived for the calculation of …

The voltage generated in a noncentrosymmetric crystal due to the bulk photovoltaic effect
(BPE) can greatly exceed the energy gap, however, the light energy conversion efficiency is …

Ferroelectric materials have been a focus of much research over the last few decades for
their unique piezoelectric and optoelectronic properties. Conventional solar cells have been …

When uniform strain is applied to noncentrosymmetric semiconductor crystals, which are
piezoelectric, static polarization charges are induced at the surface. If the applied strain is …

A well-defined ring of anisotropically scattered light is observed when a linearly polarized
laser beam is incident upon a birefringent photorefractive crystal such as BaTiO_3 …
