Unusual vortex structure in ultrathin Pb(Zr $_{0.5}$ Ti $_{0.5}$ )O $_{3}$ films

Zhongqing Wu, Ningdong Huang, Zhirong Liu +3

Using a first-principles-based approach, we determine the ferroelectric pattern in PbZr $_{0.5}$ Ti $_{0.5}$ O $_{3}$ ultrathin film. It is found that vortex stripes are formed in the sys…

Ferroelectricity in Pb(Zr $_{0.5}$ Ti $_{0.5}$ )O $_{3}$ thin films: critical thickness and 180 $^{\circ}$ stripe domains

Zhongqing Wu, Ningdong Huang, Zhirong Liu +4

The ferroelectric properties of disorder Pb(Zr $_{0.5}$ Ti $_{0.5}$ )O $_{3}$ thin films are investigated with Monte Carlo simulations on the basis of a first-principles-derived Hamiton…

Structural Trends Interpretation of the Metal-to-Semiconductor Transition in Deformed Carbon Nanotubes

Jun-Qiang Lu, Jian Wu, Wenhui Duan +2

Two mechanisms that drive metal-to-semiconductor transitions in single-walled carbon nanotubes are theoretically analyzed through a simple tight-binding model. By considering simpl…
