Unusual Compression Behavior of Columbite TiO2 via First-Principles Calculations
Xiang-Feng Zhou, Xiao Dong, Guang-Rui Qian +3
The physical mechanisms behind the reduction of the bulk modulus of a high-pressure cubic TiO2 phase are confirmed by first-principles calculations. An unusual and abrupt change oc…
The electronic structures and magnetic properties of perovskite ruthenates from constrained orbital hybridization calculations
Xiangang Wan, Jian Zhou, Jinming Dong
We introduce a method to analyze the effect of hybridization by shifting corresponding atomic levels using external potentials. Based on this approach, we study perovskite ruthenat…
Enhancement of ferroelectricity in Cr-doped Ho_2Ti_2O_7
X. W. Dong, S. Dong, K. F. Wang +2
A series of polycrystalline pyrochlore rare-earth titanate Ho_{2-x}Cr_xTi_2O_7 are synthesized in order to enhance the ferroelectricity of pyrochlore Ho2Ti2O7. For the sample close…
Ab initio study of the formation of transparent carbon under pressure
Xiang-Feng Zhou, Xiao Dong, Guang-Rui Qian +3
A body-centered tetragonal carbon (bct-Carbon) allotrope has been predicted to be a transparent carbon polymorph obtained under pressure. The structural transition pathways from gr…
