Abstract

We have investigated self organization of novel FeGe/FeSi/FeGe layered structures on Ge(111) and their electrical conduction properties. From analyses of compositional change, diffusion dynamics analyses and microstructure observations, it was revealed that the self organization of the layered structures was enhanced by spinodal decomposition which may be induced by pronounced compositional changes associating to inhomogeneous interdiffusion. The electrical conduction showed singular temperature dependence which obviously reflected natureof Kondo insulator FeSi.
