项目摘要

1.Electronic excited states in solid surfaces and interfaces have been studied with use of optical methods both from individual specialized research works performed by the participating investigators and from the efficient combination of their works. The objective of this research work is to make the basis and the future guiding principle for the studies on the above research project. Many valuable results are obtained and the necessity of the further progress in this field is emphasized.2.Following important subjects have been especially studied both from theoretical and experimental points of view. (1)Characteristics of surface excitons and exciton polaritons on semiconductor surfaces and surface plasmons on metal surfaces, and their relation with various surface phenomena. (2)Charge transfer states in the interfaces between semiconductor (or metal) and adsorbed organic dye molecules and their relations with photo-sensitization and surface enhanced Raman scattering. (3)Electronic exc … More ited states in ultra-thin films of semiconductots and their relaxation processes. (4)Quantum size effect and surface effect on excitons in semiconductor ultra-fine particles, and the effects of particle size and existence of interface on the relaxation processes of excitons.3.The progress of the research works was once examined in September, 1986, and further development has been performed. The obtained results have been presented in the final joined meeting held in January, 1988 with 37 participants. The enthusiastic and fruitful debates have established the mutual understanding among the participants on the project of this research work and also have given contribution to the development for each subject. At the same time many problems to be solved and policy and the guiding principle of further research works have been made clear.4.For further development of this research project, individual and co-operative research works, in which many specialized researchers in this field can join together, should be indispensable in very-near future.
