are semiconductors charged? i mean '"n" type contains excess of electrons, so they should be charged...
please tell me where i am wrong
tks for any answer...

Semiconductors are materials that have properties in between those of conductors and insulators. They are used in many electronic devices because they can be manipulated to conduct or block electricity, making them essential for creating electronic circuits.
Semiconductors can become electrically charged through a process called doping. Doping involves adding impurities to the material, which creates an imbalance of electrons and holes (positively charged spaces) within the semiconductor. This imbalance allows for the flow of electricity.
N-type semiconductors have been doped with an element that has extra electrons, creating a negative charge. P-type semiconductors have been doped with an element that has fewer electrons, creating a positive charge. The type of dopant used determines the electrical properties of the semiconductor.
Semiconductors control the flow of electricity through a process called bandgap. In a semiconductor, there is a small energy gap between the valence band (where electrons reside) and the conduction band (where electrons can move freely). By applying energy, in the form of heat or electricity, the electrons can jump across this gap and conduct electricity.
Semiconductors are used in a wide range of electronic devices, including computers, smartphones, televisions, and solar cells. They are also used in transistors, diodes, and integrated circuits, which are essential components in electronic devices.
