Abstract
Self-organizing properties of materials can be used to fabricate well-ordered nano- structures on a large scale and also to develop new advanced materials. Three examples of self- organized nano-structures are described in this paper. A unidirectionally ordered metallo phthalocyanine thin film was formed over the entire surface of a sapphire (1102) substrate by using a newly synthesized dibenzo[ b,t] phthalocyaninato-Zn(II), which has a unique two-fold symmetrical molecular structure. A buried SiO2 layer with atomically abrupt Si/SiO2 interface was formed by oxygen ion implantation into silicon and subsequent annealing. A nano-particle consisting of outer graphitic shells and a core nano-crystal of LaC2 was formed in a self-organizing manner when a hot carbon-langhanum particle was cooled on an arc-discharge electrode in a He atmosphere.
