Q16. The electron dispersion relation for a one-dimensional metal is given by 6260 sin ka 2Sin ka where k is the momentum, a 1s the lattice constant, e 1s a constant having dimensions of energy and ka T. If the average number of electrons per atom in the conduction band is 1/3, then the Fermi energy is (a) E,/4 (b) E (C) 26,/3 (d) 56,/3 Ans. (a)
