17:00 - 18:00 Tuesday 16 November 2010 TUG P2 The International Technological Roadmap for Semiconductors (ITRS) predicts that the exponential (Moore’s Law) development of silicon integrated circuits will continue at least for the coming decade, reaching 10 nm feature sizes. What will happen beyond the 10 nm horizon is an open and very intriguing question. However, it is very likely that it will become necessary to move to alternative electron device concepts in order to push Moore’s Law any further. One of the solutions may be a development towards hybrid electronics.
Here I will give an overview of our activities in the field of hybrid spin electronics [1]. In particular, I will discuss our efforts to realize spin injection from ferromagnetic contacts into organic semiconductors [2] and carbon-based materials [3]. In the coming years bottom-up fabrication techniques and self-assembly are expected to become more important in nanoelectronic devices. Some of our activities in that direction will be discussed as well.
