InterfaceRoughness{ }#

Calling sequence

Scattering{ InterfaceRoughness{ ... } }

Functionality

Specifies the setting for the interface roughness scattering calculation.

Note that interface grading along the growth axis (due to e.g. interdiffusion) has to be specified in InterfaceWidth

Properties

  • usage: \(\mathrm{\textcolor{ForestGreen}{optional}}\)

Example
Scattering{
    InterfaceRoughness{
        AmplitudeInZ =
        InterfaceAutoCorrelationType =
        CorrelationLengthInXY =
        AxialCorrelationLength =
    }
}
