SPP 1032:  Gruppe III-Nitride und ihre Heterostrukturen: Wachstum, materialwissenschaftliche Grundlagen und Anwendungen

Subject Area Physics
Term from 1997 to 2003
Project identifier Deutsche Forschungsgemeinschaft (DFG) - Project number 5467940
 
The priority programme "Group III-Nitrides" is subdivided into four areas, which deal interactively with the questions of epitaxial growth, materials characterisation, realisation of devices and theoretical modelisation. With the traditional growth techniques MOVPE and MBE simple InGaN and AlGaN heterostructures as well as complex layer structures for device applications should be realized. Equal priority should be given to homoepitaxial growth on quasisubstrates such as free standing HVPE-films and/or templates obtained by lateral epitaxial overgrowth (ELOG). This should lead to a better understanding concerning the correlation between structural quality on one hand and optical and electronical properties on the other hand on the basis of sytematic investigations. Carrier dynamics have to be analized and modelized to resolve the gain and loss mechanisms. Microscopic models for the relevant materials defects should be developed and be supported by theoretical calculations. Electronic (HFET, HBT) and opto-electronic device (LED, laser) realisation has equal importance. Important aspects such as electrical contacts, performance, stability and sources of possible degradation should be investigated including the problematic area of structuring.
