1. Material Limitations: Finding suitable materials that can support efficient tunneling at nanoscale dimensions remains a significant challenge. Research is ongoing to identify materials with the right properties. 2. Fabrication Complexity: The manufacturing process for TFETs is more complex compared to traditional transistors, which can increase production costs. 3. Performance Issues: While TFETs excel in low-power applications, their performance in terms of speed can be lower than conventional transistors. Optimizing performance without sacrificing energy efficiency is a key area of research.
