Two‐Dimensional Rectangular and Three‐Dimensional Rhombic Grids Created by Self‐Organization of Random Nanoextrusions

Abstract

Nanoextrusions on single crystalline Al and Al‐Mg plates under constrained cyclic tension evolve from random arrangements to regular 2D surface rectangular grid (“tweed” – A) and through gradual evolution (B) to 3D porous rhombic grid of voids (“pullover” – C). The “tweed” spacing can be decreased by loading frequency and alloy content, that could allow for the new mechanically driven method for micro and sub‐micro fabrication of 2D and 3D electronic devices.
