The exact shape of the barrier is usually modeled using self-consistent calculations - depending on the exact structures being modeled.
The height of the barrier can sometimes be worked out from the band-mismatch.
Simon Bridge said:You should be able to make out what your formulas are about by sketching the band profiles next to each other.
At the junction you'd get some band bending irl.
A potential barrier is a region in a junction where the energy of particles is higher than the surrounding areas, creating a barrier that can prevent the movement of particles across the junction.
The type of junction can affect the potential barrier as different types of junctions have different properties that can influence the energy levels and movement of particles across the junction.
Some common types of junctions that can have a potential barrier include p-n junctions, Schottky junctions, and metal-semiconductor junctions.
The potential barrier can affect the behavior of particles in a junction by either allowing or hindering their movement across the junction. It can also affect the flow of current and the overall electrical properties of the junction.
Yes, the potential barrier can be manipulated or controlled in junctions through various methods such as applying an external voltage, changing the doping levels, or introducing impurities. This allows for the customization of the junction's properties for specific applications.
