Explain the following, giving reasons:
A doped semiconductor is electrically neutral.
कारण सांगा
उत्तर
An intrinsic semiconductor possesses no fixed charges; rather, each electron originates from a broken link, which concurrently creates a corresponding hole. In this case, there are no fixed charges, and the quantities of positive and negative mobile charges are equal. Consequently, an electrically neutral semiconductor is consistently uniformly doped.
