parts‚ and Sony held a competitive advantage in the design and manufacture of those parts as a result of its accumulated expertise. In the digital era‚ however‚ complicated functionality has become concentrated in semiconductors and other key digital devices. Since‚ these semiconductors and key devices can be mass produced‚ they have become readily available to new market entrants‚ and the functionality that once commanded a high premium has become more affordable. This has led to intense price erosion

1. Introduction Blu-ray is a new optical disc standard based on the use of a blue laser rather than the red laser of today’s DVD players. The standard‚ developed collaboratively by Hitachi‚ LG‚ Matsushita (Panasonic)‚ Pioneer‚ Philips‚ Samsung‚ Sharp‚ Sony‚ and Thomson‚ threatens to make current DVD players obsolete. It is not clear whether new Blu-ray players might include both kinds of lasers in order to be able to read current CD and DVD formats. The new standard‚ developed jointly

many military applications. They will also expand the possibilities for waste heat recovery applications. The core of the solution we are proposing is a metal/semiconductor nanocomposite that will allow us to modify four intrinsic material properties in order to fabricate more efficient thermoelectric systems. The concept of a metal/semiconductor nanocomposite as a solid-state thermionic material represents a radical alternative to conventional homogeneous thermoelectric materials. Instead of focusing
