  • Patent number: 6861271
    Abstract: Indium Nitride (InN) and Indium-rich Indium Gallium Nitride (InGaN) quantum dots embedded in single and multiple InxGa1-xN/InyGa1-yN quantum wells (QWs) are formed by using TMIn and/or Triethylindium (TEIn), Ethyldimethylindium (EDMIn) as antisurfactant during MOCVD growth, wherein the photoluminescence wavelength from these dots ranges from 480 nm to 530 nm. Controlled amounts of TMIn and/or other Indium precursors are important in triggering the formation of dislocation-free QDs, as are the subsequent flows of ammonia and TMIn. This method can be readily used for the growth of the active layers of blue and green light emitting diodes (LEDs).

  • Patent number: 6859792
    Abstract: A license management method specifies a predetermined number of assigned units for each of a plurality of individually selectable programs in a product suite. A discrete node running total equals the assigned units of the highest assigned units program running on each node. Each node can run additional programs where the assigned units of the additional programs are equal to or less than the node running total without changing the node running total. Termination of the highest assigned units program on a node causes the difference between the assigned units of the terminated program and the next highest assigned units of a program running by the node to be re-added to the available units.
