Can dielectric constant of semiconductor be calculated or estimated?

  1. Aug 21, 2011 #1
    Greetings,

    Could anyone help to tell me how to estimate the dielectric constant of cobalt oxide?
    Cause I have looked for the database, and couldn't find the data.

    Very thanks,
    jovis

    As a first approximation, you could use the http://en.wikipedia.org/wiki/Clausius%E2%80%93Mossotti_relation" [Broken]. The best approach typically though is to use experimentally measured values found in handbooks such as the CRC handbook.

    Hi chrisbaird,

    Thanks a lot for your reply. I just checked the CRC handbook for the dielectric constants of cobalt oxide. But it seems to me it has only a very rough value, 12.9 within the frequency between 10^2-10^10.

    I wonder if there is data of complex dielectric constant verse wavelength or frequency.

    Thanks a lot,

    You will probably need to find a paper in a scientific journal for such comprehensive information.

    You may not like this answer, but: If you need high-accuracy, high-resolution dielectric constant values over many frequencies, and you cannot find it in the scientific literature, you may need to hire a laboratory to take the measurements for you.
