A U.K.-Portuguese research group is proposing a new solar cell design based on diffraction gratings – optical components that split and diffract light into several beams. They claim this could lead to ...

Fundamentals of electron diffraction -- Relation between crystal lattice, stereographic projection and reciprocal lattice -- Indexing polycrystalline and single-crystal patterns -- Orientation ...

A pattern of distorted lines is visible as a reflection in this close-up view of a human eye. By observing the deformation of illumination patterns reflected off the eye's surface, researchers in ...

Optics meets 2D materials: a simple probe light beam exiting an optical moiré lattice can be chopped up into diffuse streaks or confined into a single bright spot, depending on the twist angle in the ...
