Question

Why are pure semiconductors not usually used directly in most electronic devices?

पर्याय

• Their conduction bands are full at 0 K.

• They cannot contain both electrons and holes.

• They always have intentionally added impurity atoms.

• Their conductivity is limited.

Answer 1

Pure semiconductors have limited conductivity, so they are not usually used directly in most electronic devices. Their behavior remains important for understanding how semiconductor devices work.
