The dispersion relation for inverse diamond was calculated using the plane wave method.
$\frac{a\omega}{2\pi c}$ | ![]() |
The numerically calculated density of states is,
$\frac{D}{\text{unit cell}}$ | 0 1 2 3 4 5 6 7 0 5 10 15 20 |
$\frac{a\omega}{2\pi c}$ |
A description of the calculation can be found here. The associated matlab files.
