Objective
The objective of the project is to develop for European semiconductor industry long-lived blue-emitting II-VI quantum well laser diodes which utilise novel approaches to the growth and design of the semiconductor structure to achieve a performance which will surpass that of current Japanese devices.
In order for the green-blue II-VI laser diodes to reach the stage of commercialisation, some basic problems must be solved. To tackle these obstacles, we propose that the novel 'inverted' doping structures for green-blue lasers developed at Tampere University of Technology, would be assessed and evaluated in the first phase of this project. These new structures, if found to be superior to the more conventional ones, will have the advantage of overcoming one of the three major problems concerning green-blue laser development, namely decreasing considerably the contact region degradation. The two remaining major subjects of study, the defect formation during growth and operation of the device and efficient p-doping of ZnSe based compounds, will be addressed as described in detail in the workplan. It should be emphasised that the work to be completed on these two latter topics will also be of relevance for normal structures, not only 'inverted' ones.
Combining these three methods, together with general improvements in quality of the component II-VI materials, offers the most promising approach which can be conceived at the present time to achieve a breakthrough in the development of high quality II-VI lasers. Achievement of this breakthrough is the primary aim of this Consortium; it will have tremendous commercial impact.
The work to be completed under this project comprises a series of iterations from manufacturing through structural analysis to electrical analysis and lifetime testing. Each of these tasks is to be completed at a site with the most relevant expertise among the partners. Thus clearly this exercise would not be successful without the contributions from all partners involved; in this proposed project we have assembled a team with the breadth and depth of expertise necessary to explore these ideas quickly and effectively in a European context.
