Outline of Final Research Achievements

In order to clarify the mechanism of photochromic nano particles work as a battery, I screened particles size and composition directly from plasma CVD reactor by using differential mobility analyzer. As for the particle size, I do not find particular effects on this phenomenon. On the other hand, as for the composition, I found dominant composition ratio and determined its crystal structure by XRD. Then, I calculated using density functional calculations and proposed mechanism. Electrons are held in the trap levels formed by solid solution of silicon atom into the lattice, and oxygen defects invite drastic change of ionization potential of a certain nano crystals. These phenomena are considered to result in forming quantum well and hold electrons stably.
