Yutaka Furubayashi,Taro Hitosugi,Yukio Yamamoto,Kazuhisa Inaba,Go Kinoda,Yasushi Hirose,Toshihiro Shimada,Tetsuya Hasegawa +7 more
TL;DR: In this article, anatase Ti1−xNbxO2 films with x = 0.002-0.2 have been shown to have high resistivity and transport and optical properties comparable to those of typical TCOs, such as In2−xSnxO3 and ZnO.
Journal ArticleDOI
Determination of Oxygen Nonstoichiometry in a High-Tc Superconductor Ba2YCu3O7-δ
TL;DR: In this paper, thermogravimetric measurement and chemical analysis of oxygen nonstoichiometry were made at a temperature range of 350 to 1000°C and under the oxygen partial pressure of 10-4 to 1 atm.
