A fingerprint of metal-oxide powders: energy-resolved distribution of electron traps.

Akio Nitta; Mai Takase; Mai Takashima; Naoya Murakami; Bunsho Ohtani

Here we propose a method for the identification of metal-oxide powders with the energy-resolved distribution of electron traps and conduction-band bottom position reflecting a surface structure and a bulk structure, respectively, as a fingerprint, based on the degree of coincidence for a given pair of samples, measured using newly developed reversed double-beam photoacoustic spectroscopy.
