Question

If a small amount of antimony is added to germanium crystal

the antimony becomes an acceptor atom

there will be more free electrons than holes in the semiconductor

its resistance is increased

it becomes a p - type semiconductor

Solution

there will be more free electrons than holes in the semiconductor

When a small amount of antimony is added to germanium crystal, the crystal becomes n- type semiconductor because antimony is a pentavalent substrate. It excess free electrons.
