Laser diodes are semiconductors that generate light and amplify it using repeated reflection or "optical feedback." Once the ...

Researchers have discovered a method to induce chirality in non-chiral materials using terahertz light. This groundbreaking ...

Chinese scientists make ‘super diamond’ 40% harder than real thing - Material may find applications in machining, drilling, ...

Prof. Dan Shechtman of the Technion–Israel Institute of Technology made the discovery that would later earn him the 2011 ...

Zinc sulphide exists with two different crystal structures, the cubic zinc blend (top diagram) and the hexagonal Wurtzite (lower diagram). In the zinc blend structure the sulphur ions form an fcc ...

This method is also applicable to the study of the local variation of the fine structure in a crystal lattice, and the so-called selected area micro-diffraction method, when used jointly with this ...

The researchers tested their new approach on two groups of metals: five high-melting-point metals (vanadium, molybdenum, ...

Photonic crystal surface-emitting lasers or PCSELs are laser diodes that generate laser beams through controlled light wave interaction within a photonic crystal structure. In a recent study, ...
