    Hi - just a quick question on notation. Take, for example, InxGa1-xAs . What is x? Thanks.

    x is the atomic fraction of indium, which can be anything from 0 to 1. In another words, indium and gallium are interchangeable in this compound; there isn't a rigid stoichiometry. Does this answer your question?

    Yes it does. Thanks.
