(3) The probability of quantum tunneling is =16(1)e2b where =E/V and =2m(VE)/h (i) Predict the tunneling probability produced by an STM tip that is 1A(1010m) away from a metal surface. Note that the tunneling particle is an electron m=me and typical barrier height V5eV. You may assume that the electron have a typical thermal energy of EkBT where T=300K, which is equivalent to E0.025eV, the thus VEV. (ii) Estimate the tunneling probability of a proton with thermal energy EkBT where T=300K, when it encounters a barrier of height V2E and width 1A (as is typically the case for proton tunneling in a hydrogen bonded system)
