A potential barrier of 0.4V exists across a p-n junction. If the depletion region is `4.0xx10^(-7)m` wide, what is the intensity of the electric field in this region? If an electron with speed `4.5xx10^(5)m//s` approaches the p-n junction from the n-side, find the speed with which it will enter the p-side.
Text Solution
AI Generated Solution
To solve the problem step by step, we will first calculate the intensity of the electric field in the depletion region of the p-n junction and then determine the speed of the electron as it enters the p-side.
### Step 1: Calculate the Intensity of the Electric Field (E)
The intensity of the electric field (E) in the depletion region can be calculated using the formula:
\[
E = \frac{V}{D}
