Despite their potential, nanocircuits face several challenges: - Manufacturing Precision: Achieving consistent and precise placement of nanomaterials is extremely difficult. - Material Stability: Nanomaterials can be unstable and may degrade over time. - Heat Dissipation: Managing heat at the nanoscale is a significant issue due to the high density of components. - Quantum Effects: At the nanoscale, quantum mechanical effects become significant and can interfere with circuit performance.
