One-step epitaxy of high-mobility La-doped BaSnO3 films by high-pressure magnetron sputtering
Ruyi Zhang, Xinyan Li, Jiachang Bi +7
As a unique perovskite transparent oxide semiconductor, high-mobility La-doped BaSnO3 films have been successfully synthesized by molecular beam epitaxy and pulsed laser deposition…
Electron carrier-mediated room temperature ferromagnetism in anatase (Ti,Co)O2
Tomoteru Fukumura, Yoshinori Yamada, Kazunori Ueno +7
Since the discovery of room temperature ferromagnetism in (Ti,Co)O2, the mechanism has been under discussion for a decade. Particularly, the central concern has been whether or not…
The role of Cr substitution on the ferromagnetic properties of Ga1-xCrxN
R. K. Singh, Stephen Y. Wu, H. X. Liu +3
Angular-dependent channeling Rutherford Backscattering Spectroscopy (c-RBS) has been used to quantify the fraction of Cr atoms on substitutional, interstitial, and random sites in…
Observation of ferromagnetism above 900 K in Cr-GaN and Cr-AlN
H. X. Liu, Stephen Y. Wu, R. K. Singh +6
We report the observation of ferromagnetism at over 900K in Cr-GaN and Cr-AlN thin films. The saturation magnetization moments in our best films of Cr-GaN and Cr-AlN at low tempera…
Synthesis, characterization and modeling of high quality ferromagnetic Cr-doped AlN thin films
Stephen Y. Wu, H. X. Liu, Lin Gu +6
We report a theoretical and experimental investigation of Cr-doped AlN. Density functional calculations predict that the isolated Cr t2 defect level in AlN is 1/3 full, falls appro…
