Outline of Final Research Achievements

Molybdenum blue bronze (MBB) is a CDW (charge density wave) material and its nanosized particles are expected to exhibit good photo-response and ballistic electron conduction. We revealed the formation mechanism of MBB nanoribbons and succeeded in finding out suitable conditions of their single-phase or nearly single-phase preparations.
Furthermore, we succeeded in preparing various kinds of partially reduced alpha-MoO3 nanoribbons, the formation of which was found in this research program, and revealed they exhibit interesting properties for various gas detections.
