What are the Challenges in Ultrathin Film Technology?
Despite their advantages, the fabrication and utilization of ultrathin films come with several challenges:
Uniformity: Achieving uniform thickness across large areas is difficult but crucial for device performance. Adhesion: Ensuring strong adhesion between the ultrathin film and the substrate can be problematic. Stability: Ultrathin films are often prone to degradation over time, especially under harsh environmental conditions. Cost: The advanced techniques required for fabrication can be expensive, limiting their widespread adoption.
