electron_mobility{ }¶

Calling sequence

currents{ electron_mobility{ } }

Properties

using: \(\mathrm{\textcolor{ForestGreen}{optional\;within\;the\;scope}}\)
items: \(\mathrm{maximum\;1}\)

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
    }
}

Nested keywords

low_field_model¶

Calling sequence

currents{ electron_mobility{ low_field_model } }

Properties

using: \(\mathrm{\textcolor{WildStrawberry}{required\;within\;the\;scope}}\)
type: \(\mathrm{choice}\)
choices: constant; masetti; arora; minimos

Functionality

Selects low-field model for electrons.

choice	model	database
`constant`	Constant model	database{ …{ mobility_constant{} } }
`masetti`	Masetti model	database{ …{ mobility_masetti{} } }
`arora`	Arora model	database{ …{ mobility_arora{} } }
`minimos`	MINIMOS 6 model	database{ …{ mobility_minimos{} } }

Example

currents{
    recombination_model{}
    electron_mobility{
        low_field_model = masetti
    }
}

high_field_model¶

Calling sequence

currents{ electron_mobility{ high_field_model } }

Properties

using: \(\mathrm{\textcolor{ForestGreen}{optional\;within\;the\;scope}}\)
type: \(\mathrm{choice}\)
choices: none; haensch; canali; transferred; eastman; eastman4
default: none

Functionality

Selects high-field mobility model for electrons.

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
