Consider two identical conducting wires, lying on the x axis and separated by an air gap of thickness L=1nm. The work function of the metal is W=5 eV. (a) Find the probability that the electron will emerge on the other side of the barrier? (b) Find the electric field needed to allow the tunneling probability of 10-5.
