Constructor & Destructor Documentation

◆ LayerRoughness()

LayerRoughness::LayerRoughness	(	double	sigma,
		double	hurstParameter,
		double	lateralCorrLength
	)

Constructor of layer roughness.

Parameters

sigma	rms of the roughness in nanometers
hurstParameter	hurst parameter which describes how jagged the interface, dimensionless [0.0, 1.0], where 0.0 gives more spikes, 1.0 more smoothness
lateralCorrLength	lateral correlation length of the roughness in nanometers

Member Function Documentation

◆ getSpectralFun()

double LayerRoughness::getSpectralFun ( const kvector_t kvec ) const

Returns power spectral density of the surface roughness.
