An 80 eV electron impinges upon a potential barrier 100 eV high and 0.2 nm thick. What is the probability the electron will tunnel through the barrier? A)10% B)1.0% C)0.10% D)1.1 x 10^-4 % E)7.7 x 10^-10%

Question

Quizplus · Accepted Answer

The tunneling probability can be calculated using the formula for quantum tunneling, which involves the exponential decay of the wave function inside the barrier. Given the energy and barrier parameters, the probability is approximately 1.1 x 10^-4 %.
