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 quantum phenomenon of shift photovoltaic current was predicted decades ago, but this
effect was never observed directly because shift and ballistic currents coexist. The atomic …

The optical absorption edge of undoped, lightly Al‐doped, and heavily Al‐doped Bi12SiO20
single crystals is found to be exponential and follows Urbach's rule with σ0= 0.71 at room …

When subjected to measurements of temperature‐dependent dark conductivity and
thermally stimulated currents, undoped and lightly doped Bi12GeO20 (BGO) and Bi12SiO20 …

The principal theoretical ideas concerning optical effects in photorefractive crystals that are
relevant to polarization-dependent photovoltaic currents are presented. Data resulting from …
