Abstract:
The physical properties of superconductors is not well
understood . there is no unique satisfactory model that can
explain all superconductors phenomena . there is a need to
develop theoretical models that can lead to a full unique
acceptable model .
This work aims to contribute to the superconductivity by
explaining Josephson effect on the basis of a simple quantum
model .In this simple model new Schrödinger equation is derived
from which a simple Josephson current density expression is
obtained .
This expression coincide with the usual ordinary one .
