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 ...

A polaron forms when charge-carrying particles such as electrons interact with vibrations in the atomic or molecular lattice of a material. Imagine a phone ringing in a packed auditorium during a ...

A novel method transforms common liquids into epsilon-near-zero materials using femtosecond laser pulses, enabling unique ...

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 ...

A new research paper titled “Thickness-dependent polaron crossover in tellurene” was published by researchers from Rice University, Lawrence Berkeley National Laboratory, MIT, Argonne National ...

A polaron emerges when charge-carrying particles, like electrons, interact with vibrations in a material's atomic or molecular lattice. It’s akin to a phone ringing in a crowded auditorium during a ...
