Research Abstract

"Fractal" is characterized by self-similar geometry with no-periodicity. Therefore the electronic states in fractal structured lattice can be expected to show complicated structures comprising localized states and quasi-coherent states. In this study, static and dynamic control of the electronic states by introducing fractal nature into semiconductors has been investigated theoretically and experimentally. Fractal structured semiconductor superlattice show particular subband formation due to quasi-coherent states. In addition, the evidence has been given that transition between quasi-coherent and localized states under low electric filed is possible in fractal structured semiconductor superlattice.
In order to further systematic investigation and the improvement of controllability as a purpose concerning the fractal structure introduction, we proposed that the fractal dimension, which characterizes fractal structure, is applied to the advanced functional material creation system based on atomic layer epitaxy (ALE) In addition, we proposed that self-organized materials and their formation processes are characterized quantitatively using the fractal dimension as a parameter of the physical properties. Also ErSiO self-organized superlattice semiconductor, which shows the superior luminous quality, was discovered in the middle that inspects the self formation of Si related materials. ErSiO self-organized superlattice is attracting increasing attention in the fields of "silicon photonics"
