Researchers can now fabricate a 3D chip with alternating layers of semiconducting material grown directly on top of each other. The method eliminates thick silicon substrates between the layers, ...
Scientists have developed the first electrically pumped continuous-wave semiconductor laser composed exclusively of elements from the fourth group of the periodic table -- the 'silicon group'. Built ...
In recent years, the world has turned its eyes towards the remarkable properties and applications of rare earth metals, with one element in particular drawing increasing attention: germanium. Once a ...
