  • Semiconductor conductive layers
    Patent number: 7583715
    Abstract: Structures and methods for electronic devices with improved conductive regions are provided. The conductive region may include digital alloy superlattice structures, which allow higher doping levels to be achieved than for a bulk (random) alloy with the same average composition. Furthermore, the superlattice structures may improve the resistivity of the region, improving the current spreading of the region and hence the electronic properties of electronic devices such as optoelectronic devices.
