NEET Physics (general) MCQ Question
Consider a p-type semiconductor material doped with trivalent acceptor atoms. If a schematic diagram of this material shows the fixed core of the substituent acceptor with one effective additional negative charge, what is the significance of this representation?
It represents the presence of a hole associated with each acceptor atom.
It indicates that each acceptor atom contributes two electrons to the conduction band.
It signifies the formation of a covalent bond between the acceptor atom and the silicon lattice.
It suggests that the acceptor atom has gained an extra electron, making it negatively charged.
Correct Answer
Detailed Explanation
The schematic representation of a p-type material shows the fixed core of the substituent acceptor with an additional negative charge, indicating the presence of a hole associated with each trivalent acceptor atom doped in the tetravalent silicon lattice.
