Doping of silicon (Si) with indium (In) leads to the formation of

Step-by-step solution

Silicon (Si) belongs to Group 14 of the periodic table and has 4 valence electrons. Indium (In) belongs to Group 13 of the periodic table and has 3 valence electrons. When silicon is doped with indium, the indium atoms replace some silicon atoms in the crystal lattice. Since indium has only 3 valence electrons, it can form covalent bonds with only 3 neighboring silicon atoms. This leaves one valence bond incomplete, creating a vacancy or a hole in the crystal lattice. These holes act as charge carriers and move thr
