  • Device of semiconductor materials formed on a substrate having a different lattice parameter and application to a laser
    Patent number: 5012476
    Abstract: A device for use as a laser includes a component (C) of semiconductor material formed on a substrate (1) having a different lattice parameter. The substrate (1) is covered with a silicon layer (2) which is in turn covered with a matching superlattice (3) on which the component (C) is formed. The device is more particularly applicable to a component formed on diamond.
