Neutron scattering and computational modeling have revealed unique and unexpected behavior of water molecules under extreme confinement that is unmatched by any known gas, liquid or solid states. In a paper published in Physical Review Letters, researchers at th...
Light drives the migration of charge carriers (electrons and holes) at the juncture between semiconductors with mismatched crystal lattices. These heterostructures hold promise for advancing optoelectronics and exploring new physics.

Epitaxy, or growing crystalline film layers that are templated by a crystalline substrate, is a mainstay of manufacturing transistors and semiconductors. If the material in one deposited layer is the same as the material in the next layer, it can be energetically fav...

Oak Ridge National Laboratory scientists combined imaging techniques to measure crystallization kinetics of perovskite films following exposure to a mixed halide vapor.

Researchers at the Department of Energy’s Oak Ridge National Laboratory have found a potential path to further improve solar cell efficiency by understanding the competition among halogen atoms during the synthesis of sunlight-absorbing crystals.

When lots of energy hits an atom, it can knock off electrons, making the atom extremely chemically reactive and initiating further destruction. That’s why radiation is so dangerous. It’s also why high-resolution imaging techniques that use energetic electron beams ...
