Question

Magnesium (Mg) forms a hexagonal close-packed (hcp) structure with in-plane lattice constant a = 0.317 nm. Assuming that each atom is divalent (contributes two conduction electrons) and that the free-electron model applies, what is the approximate Fermi temperature of Mg?

Step 1

The volume of a hexagonal close-packed (hcp) unit cell can be calculated using the formula: V = (3√2)a^2(c/2) where a is the in-plane lattice constant and c is the height of the unit cell. Given that a = 0.317 nm and in an hcp structure, c = √(8/3)a, we can Show more…
