    Temperature mobility degradation factor (c) - MOSFET SOI

    There is an equation that I can't find in any book or scientific article referring to the letter '' c '', what is the origin of it if there is a calculation behind or something? I would very much like that source that explains itself broadly on the subject. Or at least the equation of (c).

    It is related to zero temperature coefficient [ZTC]


    Eq:

    μn2 = μn1*(((T1)/(T2)))^(c)

    Re: Temperature mobility degradation factor (c) - MOSFET SOI

    This is an empirical equation or model, describing a temperature dependence of carrier mobility.
    Mobility decreases with temperature, that's it.
    "C" is a fitting parameter, that hsould be found from fitting the model to the measured characteristics.

    Thank you very much for your help.
    If you can indicate a reference book or article say about point that it is impiric.

    Really did not find.

    Re: Temperature mobility degradation factor (c) - MOSFET SOI

    Any textbook on semiconductor physics will have something on this topic.

    Or you can look it up at Wikipedia:

    https://en.wikipedia.org/wiki/Electron_mobility

    Check the section on "Temperature dependence".
