(a) What is quantum tunneling? (b) Based on the concept of quantum tunneling, describe the working principle of a scanning tunneling microscope. (c) Explain what is quantum confinement? (d) You have a metallic nanowire. The length of the nanowire is 1 mm (Comparing with the wave length of electrons, you can think the length is infinitely long.) The width of the nanowire is 50 nm. The height of the nanowire is 20 nm. Based on the simple model we discussed...
