| Research Abstract |
The program was launched in September, 2002, with the aim of developing knowledge needed to significantly enhance performance of and aggressively exploit new functionality in semiconductor-based nano-structures with spin degree of freedom. The program was initiated with 19 research proposals, and lately expanded to 33 (32) proposals in April, 2003 (2004). The entire budget was 790 million yen for four years.
Investigators have pursued both theoretically and experimentally the advanced materials, nano-structures, and physics for spin-based photonic and electronic devices, incorporating quantum manipulation of spins. As a whole, the spirit of the program was set to move forward from the research phase of "materials and physics" to the research phase of "functionality".
Technical meetings were held twice a year, in which hot results were exchanged and discussed very effectively. In addition, five domestic symposiums and two international conferences, all of which were open to public, were held, and they successfully worked as the forum of exchanging scientific progresses made by both program members and those in the circumference of the program.
Technical achievements are summarized as follows :
1. Room temperature ferromagnetism is possible with semiconductor-based materials.
2. New functionality can be obtained by spins in semiconductors.
3. Performance based on spins can be demonstrated by realistic device structures.
The program took a major role to run two international conferences ; Spintech-III was held in August, 2005, at Yume-butai in Awaji Island, and PASPS-IV (Forth International Conference on Physics and Applications of Spin-Related Phenomena in Semiconductor) in August 2006, at International Center in Sendai. Achievements accomplished by this program were presented in these conferences, through which significant contributions has been made to the world-of science and technology.
