Notation for semiconductor alloy

Click For Summary
SUMMARY

The notation InxGa1-xAs represents a semiconductor alloy where 'x' denotes the atomic fraction of indium, ranging from 0 to 1. This indicates that indium and gallium can be interchanged within the compound without a fixed stoichiometry. The flexibility in the composition allows for various properties of the alloy to be tailored for specific applications.

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