You don't understand the difference btw a research paper and a product launch. A paper is to provide inspiration. In this case, a high ZT p-type crystal may indicate a new mechanism that can be applied to searching / designing new thermoelectric materials. It's not for selling you a working device that can be put in your shopping cart. (I did research in nano thermoelectrics and published a few papers in this field)
