PARSEM is a Marie Curie Research Training Network supported by the European Community's Sixth Framework Programme. The network contract (MRTN-CT-2004-005583) was concluded between the European Commission and consortium on 1st March 2005 with duration of 48 months.

Overall Objectives

The project aims to provide profound knowledge on III-V semiconductor heterostructures-nanostructures leading to extensive comprehension of growth mechanisms, microstructures and interfacial phenomena, as well as of the interrelation between structural and physical properties. Through such research it will be possible to control at the atomic level the synthesis, growth, processing and properties of novel III-V semiconductors that are promising for the realisation of devices for the next generation of optoelectronic applications in UV to near IR wavelengths (e.g. light emitting diodes - LEDs, laser diodes - LDs, UV detectors), and of high temperature, high frequency and power electronics like high electron mobility transistors. Such semiconductors will be III-nitride alloys and dilute nitride alloys. The particular research objectives are

• I. Development of growth techniques and determination/control of growth processes

• II. Comprehension of atomic structures, defects and interfacial phenomena

•  Analysis of the physical properties

•  Development of models of atomic and electronic structures and growth processes

Through the above objectives, binary, ternary, and quaternary III-nitride alloy compositions and dilute nitride alloys will be elaborated for quantum well (QW), quantum wire (QWR) and quantum dot (QD) heterostructures-nanostructures. In addition progress in the development of high-quality substrates leading to significantly reduced defect densities and non-polar crystal growth will be pursued. Also InN films and InN-based heterostructures will be grown to explore the applicability of this relatively less studied material.

An important target is to contribute to the advancement and defragmentation of competitive European research in materials science and technology for device applications. The most important objective is the training of a number of young researchers so that they become capable of employing a unique combination of growth, experimental characterisation, and theoretical modelling techniques, as well as additional important skills e.g. in communication and science project management.
