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 ...

The diffraction grating of a spectrometer partially determines the optical resolution that can be achieved by the spectrometer and also determines the wavelength range. Selecting the correct grating ...

Wave-particle duality is a fundamental fact of the Universe. But we don’t see many objects moving around as waves. This is why it hurts when a golf ball hits you on the head: you and the golf ball are ...

DigiLens, of Sunnyvale, California, US, has developed a liquid crystal-based lens that provides customized diffraction gratings depending on which of its layers are 'switched on'. The application ...

X-ray crystallography is a powerful non-destructive technique for determining the molecular structure of a crystal. X-ray crystallography uses the principles of X-ray diffraction to analyze the sample ...

In this article, we explore how X-ray diffraction, also known as XRD, can be used to analyze thin films and the benefits of using this technique. Many materials are now processed in the form of thin ...
