Though single crystals were once thought to be too fragile for flexible applications, the UMass Amherst team found that crystals ranging in thickness from about 150 nanometers to 1 micrometer were thin enough to be wrinkled and applied to any elastomer substrate.

«Although Al2O3 has electrically insulating properties, it can still be used as a buffer layer between the semi-conductive perovskite and the conductive contacts by limiting the thickness of the layer to one nanometer or less,» says first author Dibyashree Koushik (TU / e).

The nanosheet is made up of flakes, which are just several nanometers (one billionth of a meter) in thickness with tiny holes.

When the layers have thicknesses below the wavelength of visible light — 400 - 700 nanometers — they interact with its wave properties rather than treating it as a straight ray.
