← ScienceWhich outcome limits the current capacity when dopants segregate in a semiconductor lattice?
A)Reduced mean free path✓
B)Increased dielectric strength
C)Enhanced electron tunneling
D)Improved thermal conductivity
💡 Explanation
Reduced mean free path impedes electron flow because the dopant segregation disrupts the crystal lattice's periodicity, increasing scattering via alloy scattering. Therefore, the current reduces rather than other potential conduction effects occur because of disorder.
