Question

Q] The addition of aluminium in the crystal lattice of Germanium gives rise to which type of semi - conductor ?
a ] p - type
b ] n - type
c ] n - pjunction
d ] super conductor​

Answer 1

Answer:

a] p-type

Explanation:

Because it produce a hole or electron deficiency.

Answer 2

Aluminum doping of germanium crystal lattice creates p-type semiconductor

• A p-type semiconductor is formed when a semiconductor (usually silicon or germanium) is doped with an element from group 13 (B, Al, Ga, In, Tl)
• These elements have a valency of 3 and doping with these creates holes in the semiconductor ( lacking in electrons)
• Thus, the answer is (Option a) p-type - aluminum doping of germanium crystal lattice creates a p-type semiconductor
