Which risk increases when an electron's de Broglie wavelength approaches the Debye length in a semiconductor?

💡 Explanation

Increased electron-phonon scattering occurs when the electron's de Broglie wavelength nears the Debye length due to increased wave-like interactions. This amplifies lattice vibration coupling through Phonon interaction, because energy dissipation escalates locally due to scattering, therefore mobility decreases, rather than enhancing breakdown strength.
