Grain boundaries in graphene do not affect spin transport

Researchers from the ICN2 Theoretical and Computational Nanoscience Group as well as the Université catholique de Louvain have used numerical simulations to show that spin diffusion length is independent of grain size. The ...

Acoustic emissions unveil internal motion in granular materials

When confronted with a heavy load or deformed by stress, the individual particles in a granular material will sometimes reorganize to a more stable arrangement. At small scales these reorganizations are little more than the ...

Lead halide perovskites are not ferroelectric

In a solar cell, when the sunlight impacts the material, a charge is generated. Specifically, this charge corresponds to an electron-hole pair, where an electron is excited to the conduction band, leaving a hole in the valence ...
