Abstract
The porous silicon tube structures, with a diameter of 20 μm, were formed by pulsed anodization process. A phenomenological mechanical model was used to explain the formation mechanism. The agreement between the experimental data and theoretical results indicated that the stresses in parallel and perpendicular directions of the nanocolumnar structure may cause the crack and curve of the porous silicon layer to form the tube structures.
