ElementNNTBTable¶
- class ElementNNTBTable(onsite=None, nn_distance=None, cut_off=None, offsite=None)¶
Class for representing the slater koster table of a one element nearest neighbor tight binding model.
- Parameters:
onsite (
SlaterKosterOnsiteParameters
) – The onsite parameters describing the element.nn_distance (PhysicalQuantity of type length) – The nearest-neighbor distance.
cut_off (PhysicalQuantity of type length) – The cut-off distance, outside which matrix elements are zero.
offsite (dict) – A dict, where the keys are allowed angular momentum labels for SK models, e.g.
"sss"
,"s1ds"
, etc. and the values the corresponding matrix elements as PhysicalQuantity objects of type energy.
