Semiconductors play a vital role in modern electronics due to their ability to manipulate the flow of electricity under specific conditions. They can be broadly classified into two categories: intrinsic and extrinsic semiconductors. Intrinsic semiconductors, such as pure silicon or germanium, possess limited conductivity because their valence band
