Optical properties selection
Checking the Optical properties checkbox on the Properties tab displays options for calculating electronic intraband transitions.
Energy range: Specify the maximum energy above the Fermi level for which optical properties will be calculated. Default = 10 eV.
It is important to include a significant number of empty bands when calculating optical properties. The exact number required will depend on the nature and size of the system under consideration.
k-point set: Specify the quality of the k-point set for the optical properties calculation. Each setting corresponds to a particular separation between neighboring k-points in the Monkhorst-Pack grid. Default = Medium.
More...: Provides access to the CASTEP Optical Properties Options dialog, which allows you to set additional parameters, including the k-point set specification.
