A . . . B .
7.2.1 The figures show the "sommerfeld" picture of the ground state in the Sommerfeld model for two different two-dimensional systems. The area displayed is the range -2 (1/A) < kx, ky < +2 (1/A).
A) What is the ratio of the Fermi energies for the two systems?
B) What is the ratio of the linear dimensions of the confining potential (the box sizes) for each?
C) What is the Fermi energy and box size for Figure B?
