How to get the semiconductor alloys parameters?

  1. Jan 22, 2009 #1
    I'm working on some calculations on Al0.35Ga0.65As & In0.65Al0.45As.
    Someone can tell me where i can find the elastic/piezoelectric/dielectric constants for these rare alloys?? A database for them exist for us to search??
    Thx...

    Maybe you can find some info in the database of the Ioffe institute:

    http://www.ioffe.ru/SVA/NSM/

    The section about properties of semiconductors or the n,k-database should have some data on AlGaAs. Whether there is also info on InAlAs, I am not sure.

    The properties can be found by linearly interpolating between the two extremes i.e. AlAs and GaAs, same for the other materials.
