Several factors contribute to performance degradation: - Environmental Factors: Temperature fluctuations, humidity, and exposure to chemicals can accelerate degradation. - Mechanical Stress: Repeated mechanical stress can lead to wear and tear at the nanoscale, affecting performance. - Electromigration: In electronic nanodevices, the movement of atoms due to high electrical currents can cause degradation. - Material Aging: Over time, materials can undergo changes at the molecular level, leading to a decline in performance.
