A new, useful absorption limit for ultra-thin films
Ultrathin, conductive films such as those made of graphene are widely used in modern optoelectronic devices, but it has been thought that their efficacy is fundamentally limited: they can absorb at most half of the incident ...
Graphene partially screens van der Waals interactions depending on layer thickness, study reveals
Two-dimensional (2D) materials, which are only a few atoms thick, are known to exhibit unique electrical, mechanical and optical properties, which differ considerably from the properties of bulk materials. Some recent studies ...
Wave-like domain walls drive polarization switching in sliding ferroelectrics, study finds
Sliding ferroelectrics are a type of two-dimensional (2D) material realized by stacking nonpolar monolayers (atom-thick layers that lack an electric dipole). When these individual layers are stacked, they produce ferroelectric ...
Infrared contact lenses allow people to see in the dark, even with their eyes closed
Neuroscientists and materials scientists have created contact lenses that enable infrared vision in both humans and mice by converting infrared light into visible light. Unlike infrared night vision goggles, the contact lenses, ...
