Despite its advantages, T-NIL faces several challenges:
Mold Fabrication: Creating molds with nanoscale features can be complex and costly. Thermal Expansion: Differential thermal expansion between the mold and resist can lead to pattern distortion. Adhesion Issues: Sticking of the resist to the mold can cause defects in the imprinted pattern. Material Limitations: The choice of thermoplastics is limited to those that can withstand repeated heating and cooling cycles.
