Tunneling is important in many electronic applications. Sometimes barrier widths and heights can be changed by applied voltages, and this provides a mechanism for controlling current flow. In a certain semiconductor an electron has to tunnel through a barrier of height AE = U-E above the electron energy E. If the width of the barrier is 2.0 nm, what is the tunneling probability for AE = 1.5 eV?
