- Homework Statement
- Does an electron that is just outside the material(near the surface) on the p-side higher than that on the n-side in terms of absolute energy level?
- Relevant Equations
- N/A
When both isolated p-type and n-type materials join together and form pn-junction as picture attached, the vacuum energy level also bend so it is higher on the the p-side than on the n-side. Does that mean the absolute energy of an electron that is just outside the material on the p-side higher than the absolute energy of an electron that is just outside the material on the n-side?
