Detailed Description

template<typename DeviceType, typename ElectricFieldAccessor>
class viennashe::she::surface_scattering< DeviceType, ElectricFieldAccessor >

template<typename ElementType >

scatter_processes_type viennashe::she::surface_scattering< DeviceType, ElectricFieldAccessor >::get ( ElementType const &  elem, double  kinetic_energy, viennashe::carrier_type_id  ctype  ) const

inlineprotected

Returns all possible final scattering states for a carrier with initial kinetic energy 'kin_energy' for an edge with vertices v1 and v2.

Parameters

elem	The element for which to obtain the scattering process
kinetic_energy	Kinetic energy of the particle before scattering
ctype	Carrier type, either electrons or holes

Returns

A vector describing all possible states. For ionized_impurity_scattering we use the approximation 'incoming energy equal final energy'.
