The elastic strain sustainable in crystal lattices is usually limited by the onset of inelastic yielding mediated by discrete dislocation activity, displacive deformation twinning and stress ...

One of the tricks that researchers have used for a while now consists in reducing the motional energy of the electrons by ...

Perovskites are layered materials that have well-ordered crystal lattices. They are highly efficient harvesters of light that are being explored for use as solar cells, photodetectors ...

Birefringent crystalline materials are essential in advanced optical technologies such as isolators and modulators due to their ability to manipulate light polarization. However, designing high ...

Electron-phonon coupling (EPC) is the interaction between free electrons and phonons, which are quasiparticles representing the vibrations of a crystal lattice. EPC leads to the formation of ...

The way electrons move inside graphene—a crystal made of carbon atoms arranged in a hexagonal lattice—produces an extreme version of a quantum effect called tunneling, whereby particles can ...

The recent experiment produced a “true Wigner crystal,” according to the team, because the electrons in the lattice were functioning as a wave rather than as individual particles stuck together.

The cloud size is determined by the interaction of the electron with vibrations in the crystal lattice. Using a newly developed type of spectroscopy, Berlin researchers have shown that electrons ...

Using a trick, the physicists managed to make the regular arrangement of the electrons visible despite that small separation in the crystal lattice. To do so, they used light of a particular frequency ...

Optical lattices are much simpler than crystal lattices, as the atoms are not involved in chemical bonding. By rapidly increasing the depth of the optical lattice, the researchers create what is ...
