The phase and the group velocity of light propagating in conventional optical media cannot exceed the speed of light in ...

Polaron formation in perovskite solar cells has been indicated in scientific research as a possible factor for making this kind of cell particularly efficient, although the mechanism behind ...

In a polaron, an electron and the lattice distortion that it induces in a crystal form a 'quasiparticle'. But a strong electric field can displace the two constituents with respect to each other ...

Kunyan Zhang, Doctoral Alumna and Study First Author, Rice University A polaron emerges when charge-carrying particles, like electrons, interact with vibrations in a material's atomic or molecular ...
