Regulation of electron-electron correlation has been found to be a new effective way selectively control carrier concentration, which is crucial step toward improving thermoelectric properties. The pure electronic behavior successfully stabilized the nonambient metallic VO(2)(R) room temperature, giving excellent performance among simple oxides with wider working temperature ranges.
