Ferroelectric materials, because of their robust spontaneous electrical polarization, are
widely used in various applications. Recent advances in modelling, synthesis and …

At the end of a rush lasting over half a century, in which CMOS technology has been
experiencing a constant and breathtaking increase of device speed and density, Moore's …

A new scientific frontier opened in 2009 with the start of operations of the world's first x-ray
free-electron laser (FEL), the Linac Coherent Light Source (LCLS), at SLAC National …

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

Electromagnetic radiation in the terahertz (THz) frequency range is a fascinating
spectroscopic tool that provides resonant access to fundamental modes, including the …

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

The bulk photovoltaic effect (BPVE) refers to the generation of a steady photocurrent and
above-bandgap photovoltage in a single-phase homogeneous material lacking inversion …

We calculate the bulk photovoltaic response of the ferroelectrics BaTiO 3 and PbTiO 3 from
first principles by applying the “shift current” theory to the electronic structure from density …

Over the past few years, very interestingly, two subclasses of perovskites—organic–
inorganic halide perovskites and ferroelectric oxide perovskites, have simultaneously …

In this review we address the microscopic mechanisms that are involved in the
photogeneration processes of GHz–THz coherent acoustic phonons (CAP) induced by an …
