We present the fabrication of large-scale two-dimensional periodic silicon nanoarrays using nanosphere lithography. The techniques start from a monolayer of self-assembled polystyrene (PS) spheres of 220 nm in diameter on water surface, which works as a mask to fabricate large-scale periodic...

The adsorption of hydrogen atoms on the Ta(001)(1 × 1) surface is studied by first-principles density functional calculations within the generalized gradient approximation. It turns out that at 1 ML, coverage bridge site is energetically preferred over three-fold hollow site. This result does...

Highly ordered crystalline and amorphous Si nanoarrays have been formed by using self-assembled monolayer of polystyrene nanospheres as a template followed by dry ion etching treatments. The template was removed by annealing at 8°C and pattern transfer process was revealed by atomic force...
