SUMMARY
The built-in voltage of a P-N junction can be derived using the band diagram and the concept of Fermi energy being constant throughout the device. Additionally, it can be mathematically demonstrated by equating the drift current to the diffusion current across the junction. This derivation involves understanding the energy band structure and applying the principles of semiconductor physics. For a comprehensive mathematical proof, refer to the relevant sections of educational videos or textbooks that cover semiconductor theory in detail.
