The emergence of phage 'viruses' at MIT as the new compound tool kit or November's launch of the first nano blog to cover thin film, organic and printable electronics (http://blog.nanomarkets.net/blog/client) are just two of the deluge of nano developments all clamouring for the III-V industry's attention. However, the common thread for success with material, equipment, devices or markets, as defined by Aixtron's Rainier Beccard, is 'control in more than one dimension'. [view less]

Electronic transport characterization in semiconductor materials is becoming increasingly difficult as multi-layer and multi-carrier materials become more common. Examples include multiply doped or compensated regions, doping non-uniformities perpendicular to the conduction plane, 2D carriers at surfaces and interfaces, heterostructures, multiple quantum well structures, and ...

Electronic transport characterization in semiconductor materials is becoming increasingly difficult as multi-layer and multi-carrier materials become more common. Examples include multiply doped or compensated regions, doping non-uniformities perpendicular to the conduction plane, 2D carriers at surfaces and interfaces, heterostructures, multiple quantum well structures, and materials with carriers populating different conduction band minima or valence band maxima. The heterostructures can contain delta-doped layers only a few atoms thick sandwiched between many other layers. Knowledge of the transport properties of all carriers present can greatly aid understanding of new materials and devices, identifying processing problems, and reducing costs by identifying good material early in the fabrication process.

One of the most rapidly developing segments of the broader semiconductor industry is the telecommunications market, where manufacturers seek to profit from the huge volume of mobile phone handsets. Some 960 million handsets were shipped in the 2005-2006 period, and volume is still growing, driven in part by burgeoning sales in remote areas (some of which have never had significant landline systems), and in part by the rapid-fire addition of sophisticated new functions to the handsets. The latter is increasing in an endeavour to find that elusive 'killer application' in the commodity market. [view less]

Nippon EMC Ltd is Japan's oldest and most successful manufacturer of metal-organic phase vapour epitaxy (MOPVE) systems. The company was awarded a New Energy and Industrial Technology Development Organization (NEDO) grant for the development of hydride vapour phase epitaxy (HVPE) systems for mass production of GaN substrates. The results of the new NEDO project will contribute to increasing demands for Group III nitride-based semiconductor devices for next generation DVD, high brightness LEDs and high frequency, high power nitride heterostructure electron devices for telecoms.

Gallium nitride (GaN) is often regarded more or less as the younger brother of gallium arsenide (GaAs), and to some extent this is an accurate view. Lately, GaN has been receiving a great deal of attention, for the most part because its strong points - handling high frequencies, high power levels and higher operational linearity - are required by technologies that are now, or will soon become, significant economically.

Anyone who has ever worked for a UK Ministry of Defence supplier becomes quickly aware of the anomaly in spelling the US Department of Defense. In compound terminology, for the US, think 'defenestration' and 'window for opportunity'. For the UK, more claustrophobically, think fenced in.... [view more]

Anyone who has ever worked for a UK Ministry of Defence supplier becomes quickly aware of the anomaly in spelling the US Department of Defense. In compound terminology, for the US, think 'defenestration' and 'window for opportunity'. For the UK, more claustrophobically, think fenced in. Could this difference in attitude, which has seen the very real growth of the US compound materials and devices industry, urged on by a demanding DARPA, be about to undergo a similar revolution in the UK?

It is appropriate at this point of the magazine to wish our readers world over all the best of the season's greetings. No doubt next year will be just as exciting as 2006. Generally, it has been an interesting one, even if it has not been a financial bonanza for all. Technologically speaking, some milestones have been achieved and there are more in prospect. [view less]
