The probe passes over an atom that is 3.20×10^2 nm "tall."

The probe passes over an atom that is 3.20×10^2 nm "tall." By what factor does the tunneling current increase?

Is this your homework? What have you learned about tunneling?
 


Yes this is my homework, can you give me a hint
 


I figure it out :)

Thread 'Quantum behaviour of an electron around a positively charged sphere'

If we release an electron around a positively charged sphere, the initial state of electron is a linear combination of Hydrogen-like states. According to quantum mechanics, evolution of time would not change this initial state because the potential is time independent. However, classically we expect the electron to collide with the sphere. So, it seems that the quantum and classics predict different behaviours!
