Several mechanisms can contribute to flicker noise in nanodevices:
Defects and impurities: Imperfections in the material can trap and release charge carriers, causing fluctuations in current. Surface states: At the nanoscale, the surface-to-volume ratio is high, making surface states more influential in contributing to flicker noise. Quantum effects: Quantum fluctuations and tunneling phenomena can also play a role in flicker noise in nanodevices.
