    Problem 2 (20 pts) A scanning tunneling microscope employs a small sharp conducting tip that is brought into close proximity of a material, as TIP shown in the figure at right. The vacuum region between the tip and the sample acts as a potential barrier because the electrons in the material have a lower potential than in free space (work functions of the materials). Therefore, the current across the vacuum is proportional to the transmission probability T approximated by a...

    This is a challenging multi-step problem. Solve it on paper, writing out each step carefully. When doing calculations, do not round intermediate values. Note: If you have approached the problem in a principled way, do not abandon your approach if your numerical answer is not accepted; check your calculations! The Bohr model correctly predicts the main energy levels not only for atomic hydrogen but also for other "one-electron" atoms where all but one of the atomic electrons has been removed,...
