Consider an ideal fermi gas in 2d. it is contained in an area of dimensions l x l. the particle mass is m (a) find the density of states d(e) n/l2 (b) find the fermi energy as a function of the particle density function of the fermi energy ep (c) find the total energy as a function of n and t. (d) find the chemical potential u as a hint: note that d -1 in(e 1) dac 5 e 1
