Electrons are fired at a rectangular potential energy barrier, once every 197 ms. If the barrier is 2.55 nm thick and has a height that exceeds the energy of the incident electrons by exactly 762 meV, how long on average would you expect to wait for one electron to pass through the barrier? average wait: 19.38 x10° Incorrect
