hole_mobility{ }

Calling sequence

currents{ hole_mobility{ } }

Properties

• usage: \(\mathrm{\textcolor{ForestGreen}{optional\;within\;the\;group}}\)

• items: \(\mathrm{maximum\;1}\)

Functionality

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

Example

currents{
    recombination_model{}
    hole_mobility{
        low_field_model = constant
    }
}

high_field_model

Calling sequence

currents{ hole_mobility{ high_field_model } }

Properties

• usage: \(\mathrm{\textcolor{ForestGreen}{optional\;within\;the\;group}}\)

• type: \(\mathrm{choice}\)

• choices: none; haensch; canali; transferred; eastman; eastman4

• default: none

Functionality

Selects high-field mobility model for holes.

choice	model	database
none	High-field models are not used	—
haensch	Hänsch model	mobility_haensch{ }
canali	Extended Canali model	mobility_canali{ }
transferred	Hänsch model	mobility_transferred{ }
eastman	Eastman-Tiwari-Shur model with standard parametrization	mobility_eastman{ }
eastman4	Eastman-Tiwari-Shur model with observable parametrization	mobility_eastman4{ }

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
