Physics · Semiconductor Devices
For an abrupt p-n junction in thermal equilibrium, the built-in potential Vbi can be expressed in terms of the bandgap energy Eg and the energy differences on the n and p sides as:
- 1Eg - (qVn - qVp)
- 2Eg + (qVn + qVp)
- 3Eg - (qVn + qVp)✓
- 4qVn + qVp
Correct answer
Eg - (qVn + qVp)
