Which outcome increases when grain boundary density rises in polycrystalline silicon?

A)Minority carrier recombination rate increases
B)Hall resistance becomes negligible
C)Capacitance is unaffected overall greatly
D)Phonon mean free path increases

💡 Explanation

Increased grain boundaries elevate impurity segregation, thereby enhancing the Density of States via interface recombination, because more trap states emerge. Therefore, minority carrier recombination rate strongly increases rather than Hall resistance decreasing since conduction paths are disrupted.
