Functionality

Selects mobility models for electrons. Both low-field and high-field mobility models are possible to be selected in this group.

Example

currents{
    recombination_model{}
    electron_mobility{
        low_field_model = constant
    }
}

haensch	Hänsch model	mobility_haensch{ }
canali	Extended Canali model	mobility_canali{ }
transferred	Hänsch model	mobility_transferred{ }

Warning

Convergence may be poor or non-existent for some choices of parameters. One should pay attention to selecting high-field model which is suitable for the semiconductor system of choice
