Area of Science:

  • Materials Science
  • Nanotechnology
  • Surface Science

Background:

  • Three-dimensional hierarchical metal patterning is crucial for advanced applications.
  • Traditional methods are often complex and time-consuming, involving layer-by-layer lithography.

Purpose of the Study:

  • To develop a simplified direct nanoimprint lithography process for creating 3D hierarchical metal patterns.
