P-N Junction Diode and its applications: Practice Problem & Solution

Solution Explained:

To solve this problem, we apply the core principles of P-N Junction Diode and its applications. Understanding the underlying formula is key to arriving at the correct answer below:

The built-in barrier potential $V_0 = \frac{kT}{q} \ln(\frac{N_A N_D}{n_i^2})$. This formula shows it depends on temperature $T$, doping concentrations $N_A$ and $N_D$, and intrinsic concentration $n_i$, which depends on the material.
