First germanium tin semiconductor laser directly compatible with silicon chips

First germanium-tin semiconductor laser directly compatible with silicon chips

Electronics News Updates / By

Swiss scientists have created the first semiconductor laser consisting solely of elements of main group IV (the carbon group) on the periodic table. Simply, this means that the new device is directly compatible with other elements in that group – such as silicon, carbon, and lead – and so can be directly incorporated in a […]
