Could you make a series of wells based on probability to amplify a particle that is quantum tunneling.

 

Say you could make a well that made a certain barrier statistically for a particle to tunnel, could you on the other side of that make a similar barrier but based on a particle that has already tunneled, and in turn basically make a series of that where each barrier is based on the previous one, or would a particle that tunneled have to come out on the other side with no way to interact with the next barrier in a similar manner while being still in the state from the first tunneling event.

 

particle(A)->barrier(A)->particle(A+tunnel A)->barrier(b) and so on.

 

I don’t know if tunneling happens only at certain energies, but if there was a small range of values then I think you could take advantage of this, for what application I have no idea. Maybe if you could use it on photons it could act as a gate on behavior, but I don’t know how you could trap a photon, save for applying it to absorption and emission of photons from a quantum dot in some matrix.

 

Maybe like a circuit, but for the particle to advance it has to tunnel through a sequential amount of barriers each with a higher energy cost in regards to probability for a tunneling event, and that each is based on the energy value on the previous barrier?

 

Nevermind, google should be the first step huh.

Look up instantons and the WKB approximation.

 

You will find that the tunnelling amplitude in quantum mechanics is proportional to [math]e^{-\frac{1}{\hbar}\int_{a}^{b} \sqrt{2m(V(x)-E)}dx}[/math], where [math]a[/math] is the beginning point and [math]b[/math] the end point of the tunnelling. [math]V(x)[/math] is the potential and [math]E[/math] the energy.

I'd suggest reading about semiconductor microcavities...
