Step 1

Step 1: The maximum potential barrier rm in the presence of an electric field can be expressed as the sum of the built-in potential Vbi and the potential due to the electric field, which is given by qE*rm, where q is the charge of the carrier and E is the electric Show more…

1. Derive an expression for the maximum potential barrier rm in the presence of the electric field? 2. Evaluate rC for ε = 3 at room temperature and zero-electric field? The Coulomb radius rC is defined as when the separation between the electron and hole is such that the energy required to overcome the overall potential barrier equals the ambient temperature kT.
