Homework assignment for the week of Apr. 13:

• A monolayer of metal atoms is laid down on a flat substrate made of quartz. Accordingly, the electrons of the metallic atoms are free to move in two rather than three dimensions. In a manner analogous to that discussed in class determine a) the electron energy distribution function P(E) and plot it for T=0 and T=(Fermi Energy)/k, and b) the Fermi Energy.

• Consider a graphite crystal which consists of two-dimensional planes of hexagonal structures separated by a distance L. If the distance between the centers of adjacent atoms in the two-dimensional planes is 2R, where R is the radius of the carbon atom, and the separation between adjacent planes (atomic center to atomic center) is 4R what is the packing density of this crystal?
