AIIMS 2018 Physics Carrier Concentration MCQ Question

Option A is correct because the calculations provided demonstrate the behavior of minority carriers in semiconductor materials, specifically the transition from n-type to p-type doping. The derived values for electron concentration (nₑ) and hole concentration (nₕ) illustrate the principles of charge carrier dynamics, where the minority carrier concentration in a p-type region is significantly influenced by intrinsic carrier concentration (nᵢ) and the majority carrier concentration. The other options are not applicable as they do not provide any relevant information or alternative answers to the question posed. Understanding these concepts is crucial for analyzing semiconductor behavior in electronic devices.
