ABSTRACT: A pressure dependent Schrodinger equation is
used to find the conditions that lead to superconductivity.
When no pressure is exerted, the superconductor resistance vanishes beyond
a critical temperature related to the repulsive force potential of the electron
gass, where one assuming the electron total energy to be thermal, where
applying mechanical pressure destroys Sc when it exceeds a certain critical
value. However when the electron total energy is an assumed to be that of the
free electron model and that the pressure is thermal and mechanical, the
situation is different. The quantum expression for resistance shows that the
increase of mechanical pressure increases the critical temperature. Such phenomenon is observed in high temperature cupper group.
