Symposium_F_Program 861.60 Kb

The nitride semiconductors have emerged as important and promising materials for a wide field of optoelectronic and electronic applications. LEDs based on GaN and its alloys with InN and GaN exhibit green, blue and UV high brightness emission levels which are ready to serve many indoor and outdoor applications. Combined with the available red LEDs or by using RGB phosphors they can be used for displays as well as for illumination purpose in office, at home, in automobiles, aircraft airport runways, ships etc. Blue laser diodes based on the same material systems are already available to be used for data storage on CD ROMs with densities in excess of 1Gbite per cm2. This makes affordable high density digital information storage systems possible for a huge consumer market of movies in high picture quality on one CD ROM. Electronic devices based on Nitrides and SiC are using the superior electrical properties for high power, high frequency and high temperature applications. However, this huge potential of promising material properties and fields of applications can only be used in a wide and economic manner, if several substantial deficiencies and draw back of the materials can be overcome. These relate mostly to severe structural imperfections of the crystals and epitaxial layers and especially the lack of substrates for GaN-homoepitaxy.

Scope:

This symposium will provide a forum for active researchers in materials science and engineers working in device design, processing technologies, photonic and electronic devices of the group III-nitrides. Special emphasis on crystal polarity and their effect on the electronic properties will be placed, especially in the context of the improving the efficiency of light emitting devices operating in the green and longer range. The effect of strain resulting from lattice mismatch and thermal expansion differences will be explored. This symposium is a consequent continuation of earlier E-MRS symposia on related topics. The symposium will consist of both invited and contributed talks and poster sessions.

Hot topics to be covered by the symposium:

• Bulk growth of substrate crystals of GaN, and related alloys, including wafering
• Preparation of template substrates for GaN-based epitaxy including lift-off technology
• Epitaxial growth of nitride semiconductors, including modeling
• Optical characterization
• Defects and characterization of material properties
• Magnetic properties
• Nanostructures
• Device processing and technology and its correlation to material science, technology and materials properties
• Impact of crystal defects on device properties
• Specific processes required in wide bandgap technology (e.g. post implant annealing, etc.)
• Photonics

The proceedings of this symposium will be published in the journal Phisica Status Solidi by Wiley.
