摘要：

Formation of disordered and ordered pore patterns in two dimensions have been reported in pore growth in nanoporous alumina templates. This is explained in terms of instability in the pattern formation. Here, we report our observation of instability in the pattern formation in three dimensions, that is, along the cylindrical axis of the pores. The instability is revealed in the form of dendrites in the pore pattern under certain fabrication conditions. We examine the conditions under which two- and three-dimensional instability occurs and compare our observations of the two dimensional case with existing models in the literature.
