Figure 1From: Three-dimensional nanowire networks fabricated by ion track nanotechnology and their applicationsIrradiation scheme for network templates with intersecting pores. The polymer foils are irradiated sequentially from four different directions (a)–(d) using swift heavy ions. During each irradiation step, the foil is tilted by 45° towards the incoming ion beam.
