  • Patent number: 7122827
    Abstract: The present invention is directed toward a method for fabricating low-defect nanostructures of wide bandgap materials and to optoelectronic devices, such as light emitting sources and lasers, based on them. The invention utilizes nanolithographically-defined templates to form nanostructures of wide bandgap materials that are energetically unfavorable for dislocation formation. In particular, this invention provides a method for the fabrication of phosphor-less monolithic white light emitting diodes and laser diodes that can be used for general illumination and other applications.

  • Publication number: 20040077156
    Abstract: Methods of fabricating a semiconductor film with reduced defects comprising lithographically defined nanoscale features patterned into an underlying layer. A semiconductor film is then nucleated within the plurality of nanoscale features. The nanoscale features are aligned with specific crystallographic axes to allow for controlled growth rates. A semiconductor film produced with a greater than four orders of magnitude decrease in the threading dislocation density and thus improved optical and electrical transport properties. The invention applies to wide bandgap semiconductor films, however, also applies to any film-substrate combination where significant lattice and thermal expansion misfit occurs.

  • Patent number: 6539223
    Abstract: A mobile telecommunications system includes within a serving system database entries that associate the identifier of a mobile unit, which could be a cellular telephone or a personal communications service (PCS) device, with a plurality of directory numbers. The mobile unit identifier may be a mobile identification number (MIN) or international mobile service identifier (IMSI), for example. The system may store this association within a home location register (HLR), within a mobile switching center (MSC), or in both. In the process of terminating a telephone call the system employs supplemental information to determine which of the plurality of directory numbers associated with the mobile unit's mobile identifier is to be employed for the purposes of the telephone call being terminated. The supplemental information may be the current location of the mobile unit, for example.
