The recently discovered anomalous photovoltaic effect in ferroelectrics is attracting
considerable attention of specialists in ferroelectricity and solid-state physics. The …

Ferroelectric absorbers, which promote carrier separation and exhibit above-gap
photovoltages, are attractive candidates for constructing efficient solar cells. Using the …

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

Since Valasek's discovery of the ferroelectric properties of Rochelle salt nearly 60 years ago,
ferroelectricity has been regarded as one of the tradi tional branches of dielectric physics. It …

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 …

We show how finite-size scaling of a bulk photovoltaic effect-generated electric field in
epitaxial ferroelectric insulating BaTiO 3 (001) films and a photo-Hall response involving the …

Noncentrosymmetric bulk crystals generate photocurrent without any bias voltage. One of
the dominant mechanisms, shift current, comes from the quantum interference of electron …

The shift current (SHC) has been accepted as the primary mechanism of the bulk
photovoltaic effect (BPVE) in ferroelectrics, which is much different from the typical pn …

The applications of transition metal oxides as photovoltaic and photocatalytic materials are
mainly impeded by their poor visible light absorption, low photogenerated carrier mobility …
