I am trying to enhance the thermoelectric performance of Mg3.2Sb1.5Bi0.49Te0.01 through doping. Various researchers has optimized this material for various concentrations of Te through using Mg3.2Sb1.5Bi0.5-xTex, Mg3Sb1.5-0.5xBi1.5-0.5xTex, etc, by replacing Bi through Te. My question is that if i can substitute Sb by Te by using Mg3.2Sb1.5-0.5xTex, x=0.01,0.02....? Is its scientifically possible? if not why??
Interesting question. You might need careful x-ray measurements of single crystals to study this problem. What is the expected formal charge state of each of the elements?
I found lots of literature here:

Geoff Pain How can i understand this literature is relevant to my question. These are too many papers...
This paper might be relevant
