It was the objective of the ADMIRAL project to develop light-emitting diodes and lasers emitting in the mid-infrared (MIR) and consisting of group III-antimonide semiconductors. The devices were bipolar devices aimed at operating in the current injection mode close to room temperature (RT). The largest challenge was the deposition of the layer structures by metalorganic vapor phase epitaxy (MOVPE), a process technology which presently is most widely used for industrial application. In the future it will certainly be the technology for mass production of devices operating in the MIR. Overall project progress has been measured against four milestones, of which three have been fully completed in a successful manner. The final milestone was 80% achieved however it proved too optimistic a goal to reach RT operation within the time constraints of the project.
