Abstract
A method is provided. The method includes exposing a first material disposed across a first plane on a first substrate to an ion beam to form a first plurality of structures in the first material, the ion beam directed at the first material at an ion beam angle ϑ relative to a surface normal of the first substrate. The first substrate is positioned at a first rotation angle ϕbetween the ion beam and a first vector of the first plurality of structures, the first material is exposed to the ion beam incrementally along a first direction, and exposure of the first material to the ion beam is varied along the first direction to generate a depth variation between the first plurality of structures in the first direction.
