← ScienceWhich risk increases during high-speed electron transport in graphene?
A)Increased electron-phonon scattering✓
B)Enhanced electron-electron repulsion
C)Reduced quantum Hall effect
D)Suppressed Coulomb blockade effect
💡 Explanation
Increased electron-phonon scattering occurs because heat generates electron-phonon perturbations, rather than electron-electron. Therefore, increased resistance and heat are outcome, because phonon interactions impede electron flow where graphene layer temperature reaches extremes; rather than other conditions.
