Key Points
- Solution for electron incident on a finite barrier
produces tunneling.
- Solution for a complicated potential.
- Break problem into regions of simple potentials
- Write Sch. Eq. for each region
- Link BC's at each interface between regions (both
wavefunction and derivative)
- Solve set of linked equations.
- Sin/Cos solution for regions where E > V
- Decaying solution for regions where E < V
- Quantum mechanical tunneling is the finite probability
of a partical passing through a barrier higher then the electron
energy. Very non-classical.
