Atomically thin layers can now be formed by materials usually unknown for being two-dimensional. A quasi-2D gold film has been synthesized by researchers from the MIPT Center for Photonics and 2D Materials.

As published in Advanced Materials Interfaces, this discovery means that now quasi-2D gold can be placed on arbitrary surfaces. These nanometers-thick ultrathin gold films act as conductors of electricity and are extremely useful for see-through electronic devices.

Moreover, this new class of optical metamaterials, with their distinctive capacity to control light may create unexpected technologies - Harry Potter's cloak of invisibility comes to mind.
