New laser for computer chips: International team of scientists constructs first germanium-tin semiconductor laser for silicon chips

19 enero 2015

The first semiconductor consisting solely of elements of main group IV has been revealed by researchers. The germanium-tin (GeSn) laser can be applied directly onto a silicon chip and thus creates a new basis for transmitting data on computer chips via light: this transfer is faster than is possible with copper wires and requires only a fraction of the energy.
