NANO-STRUCTURE FABRICATION BY USING SELF-ORGANIZING PROPERTIES OF MATERIALS

Self-organizing properties of materials can be used to fabricate well- ordered nanostructures on a large scale and also to develop new advanc ed materials. Three examples of self-organized nano-structures are des cribed in this paper. A unidirectionally ordered metallophthalocyanine thin film was formed over the entire surface of a sapphire (1 (1) ove r bar 02) substrate by using a newly synthesized dibenzo[b,t] phthaloc yaninato-Zn(II), which has a unique two-fold symmetrical molecular str ucture. A buried SiO2, layer with atomically abrupt Si/SiO2, interface was formed by oxygen ion implantation into silicon and subsequent ann ealing. A nano-particle consisting of outer graphitic shells and a cor e nano-crystal of LaC2 was formed in a self-organizing manner when a h ot carbon-langhanum particle was cooled on an are-discharge electrode in a He atmosphere.
