Which risk increases when dopant concentration approaches a Mott transition?

A)Delocalized electron wavefunction interference
B)Increased electron-phonon scattering
C)Reduced overall sample capacitance
D)Interlayer dielectric structure warping

💡 Explanation

Localized electrons become delocalized due to wavefunction overlap through quantum tunneling. Higher doping causes delocalization, therefore electron interference and scattering increase dramatically, rather than predictable scattering under Boltzmann transport regimes because the Fermi level enters impurity bands.
