3. Tunnel microscope.Quantum physics.
We now turn to a more detailed discussion of effects associated with the Penetration of the wavefunction into the classically forbidden region. Consider firs a potential well bounded by barriers of finite height As we have wen in the finite square well case, Quantum
therefore implies that a particle is able to pass through a potential
barrier which, according to classical mechanics, should be impenetrable.
We consider the problem of quantum mechanical tunneling. And it ‘s also shown practical application for description of scannig tunnel microscopy
