Challenge:Approaches for ‘Large Area’ PBG Fabrication

  • Methods to form ordered, anisotropic structures

    • Microcontact printing

    • Block copolymer templating

    • Colloidal crystal processing

    • Lithography (nano)

    • Holography

    • TPA MicroFab

    • Surfactant(micelle) directed

    • Pattern-directed dewetting

    • Polyelectrolyte deposition

    • ….

  • Trade-offs

  • Cost-effect, rapid access to ‘complex’ structures

  • ‘Defect’ engineering
