Article Synopsis
- - Researchers observed ferroelectric properties in a 2D phase of water ice, created by confining it between two graphene layers at room temperature, demonstrating a strong, permanent dipole influenced by external electric fields.
- - They found that for ferroelectric ordering to occur, a monolayer of 2D ice is necessary, with findings supported by both simulations and tests on water's partial pressure and temperature.
- - The unique properties of this 2D ice allow for the development of new nanoelectromechanical devices with memory capabilities, showing significant switching performance and durability without degradation over numerous cycles.
Solid-diffusion-facilitated cleaning of copper foil improves the quality of CVD graphene.

The quality of CVD-grown graphene is limited by the parallel nucleation of grains from surface impurities which leads to increased grain boundary densities. Currently employed cleaning methods cannot completely remove surface impurities since impurity diffusion from the bulk to the surface occurs during growth. We here introduce a new method to remove impurities not only on the surface but also from the bulk.
