Nitrogen defects and ferromagnetism of Cr-doped AlN diluted magnetic semiconductor from first principles
Li-Jie Shi, Li-Fang Zhu, Yong-Hong Zhao +1
High Curie temperature of 900 K has been reported in Cr-doped AlN diluted magnetic semiconductors prepared by various methods, which is exciting for spintronic applications. It is…
Combined Raman scattering and ab initio investigation of pressure-induced structural phase transitions in the scintillator ZnWO4
D. Errandonea, F. J. Manjon, N. Garro +5
Room-temperature Raman scattering was measured in ZnWO4 up to 45 GPa. We report the pressure dependence of all the Raman-active phonons of the low-pressure wolframite phase. As pre…
Elastic properties of transition metal dioxides: XO(X=Ru, Rh, Os, Ir)
Yanling Li, Zhi Zeng
The elastic properties of rutile transition metal dioxides XO (X=Ru, Rh, Os, and Ir) are investigated using first-principles calculations based on density functional theory.…
Colossal electroresistance effect around room temperature in LuFe2O4
Chang-Hui Li, Xiang-Qun Zhang, Zhao-Hua Cheng +1
A colossal electroresistance effect is observed around room temperature in a transition metal oxide LuFe2O4. The measurements of resistance under various applied voltages as well a…
Iron-based layered superconductor LaOFFeAs: an antiferromagnetic semimetal
Fengjie Ma, Zhong-Yi Lu
We have studied the newly found superconductor compound LaOFFeAs through the first-principles density functional theory calculations. We find that the parent compound L…
Millimeter-Scale, Highly Ordered Single Crystalline Graphene Grown on Ru (0001) Surface
Y. Pan, N. Jiang, J. T. Sun +4
We demonstrate a method for synthesizing large scale single layer graphene by thermal annealing of ruthenium single crystal containing carbon. Low energy electron diffraction indic…
