  • Light emitting diode having undoped and unintentionally doped nitride transition layer
    Patent number: 8409972
    Abstract: A method of forming electronic device precursors and devices with reduced cracking in relevant layers is disclosed along with resulting structures. The method includes the steps of growing a transition layer of undoped Group III nitride on a substrate that is other than a Group III nitride, growing an active structure of Group III nitride on the undoped layer, and removing the substrate from the undoped layer.
    Type: Grant
