Question

Probability of quantum tunneling through rectangular potential barrier

Answer 1

Answer:

The transmittance T is the probability that an electron will tunnel through a barrier. The transmittance T is approximately given by the simple exponential form T = exp(-2bL) with b = (2m(U0-E)/ħ2)1/2. T depends on the difference of the electron energy E and the height of the barrier U0, and on the barrier width L.
