Several factors contribute to signal degradation in nanotechnology:
1. Thermal Noise: Due to the small size of nanodevices, thermal fluctuations can have a more pronounced effect, introducing noise that degrades the signal. 2. Quantum Tunneling: At the nanoscale, electrons can tunnel through barriers that would be insurmountable at larger scales, potentially leading to signal loss. 3. Material Impurities: In nanomaterials, even minimal impurities can significantly impact electrical and optical properties, leading to signal degradation. 4. Electromagnetic Interference: As dimensions shrink, the susceptibility to external electromagnetic fields increases, exacerbating signal degradation.
