← ScienceWhich outcome occurs when a crystalline silicon lattice contains dislocations?
A)Increased electrical resistance and brittleness✓
B)Enhanced thermal conductivity and ductility
C)Improved optical transparency shifts linearly
D)Reduced resistance to acidic chemical corrosion
💡 Explanation
Dislocations in a crystal lattice interrupt the periodic arrangement of atoms, inducing electron scattering, ultimately increasing electrical resistance through decreased mean free path and brittleness via weakened planes near it, because the process is electron scattering along disrupted atoms; therefore brittleness increases rather than increases in electrical resistance.
