Answer:

Please mark me brainliest

Explanation:

When germanium is doped with gallium which contains only three valence electrons (Group 13 element ns2 np1) the do pant atoms occupy some of the lattice sites normally occupied by germanium atom. ... These holes can move through the crystal like a positive charge and increase the conductivity of germanium crystal.
