Given a heterostructure interface (e.g. two n-type semiconductors), show how the energyband structure changes near the interface once they are attached and equilibrium isobtained. Why does this happen in terms of electron motion, “built-in” potential, maintainingband gap energy and electron affinity?

Given a heterostructure interface (e.g. two n-type semiconductors), show how the energy
band structure changes near the interface once they are attached and equilibrium is
obtained. Why does this happen in terms of electron motion, “built-in” potential, maintaining
band gap energy and electron affinity?
