摘要：

The reflectance of highly reduced SrTiO3-x has been studied in samples where the carrier concentration-or oxygen-vacancy density - varies from about 10(18) to 10(21) cm(-3). Several phonon modes are strongly influenced by oxygen-vacancy density. Oxygen reduction induces a mid-infrared band whose oscillator strength scales with carrier density. In highly reduced samples, a weakly localized plasmon mode develops. [S0163-1829(99)10919-6].
