Consider quantum tunnelling in the situation where a free particle with energy e interacts with a barrier of potential va and width l, as in section 3.3.5 of the quantum physics notes. assume the thick, high barrier approximation eve much greater than e, and llarge) l find the ratio between the tunnelling probabilities for the cases where vorband vo b/2, for some positive number b. (assume all other parameters are identical.) and l c /2 i. find the ratio between the tunnelling probabilities for the cases where l for some positive number c. (assume all other parameters are identical) ill. using your answers to i. and il, state whether the quantum tunneling probability is more sensitive to changes in voor changes in l
