Bipolar conduction effects can't be neglected in narrow-gap semiconductors and semimetals. @MichaelToriyama masterfully derived simple descriptors to predict TE performance in such materials. A collaboration w/ @SnyderGroupNU

The unusual TiFe1.5Sb semiconducting composition is a prototype for emerging low thermal conductivity Heuslers.

We find that these compounds are stabilized by Fe playing a dual role in the structure.

Big congrats to Dr. Male! @JamesMale27 I can see a nice pic at the top of Mt. Fuji! Such a fun time.

Btw today I was wearing the same matsci pullover as Prof. Wolverton do😆

[Snyder Lab @SnyderGroupNU]

Brilliant PhD defense from @JamesMale27. A masterclass on doping complex semiconductors to obtain targeted electronic and mechanical properties. Congratulations Dr. Male!

[Snyder Lab @SnyderGroupNU]

Presence of a band-gap and good thermoelectric properties simultaneously in intermetallic compounds can be surprising.

Maddie's new paper highlights how half-Heusler compounds achieve both these things with avoided crossings in the electronic structure.

The other review paper is out! My phd work was accumulated and broader perspectives on rising star Mg3Sb2 were summarized as a open access. I am open for the discussion and let me know if you have any questions!! #thermoelectrics https://t.co/r61Kvovaen

Wonderful to host @ShashwatAnand16 from @BerkeleyLab (prev. @SnyderGroupNU) for our Friday journal club. He shared his recent work on thermodynamic guidelines for maximizing dopant solubility. Thinking about defects in composition space!

[Snyder Lab @SnyderGroupNU]

Dopant solubility can often be underestimated despite the observation of impurity phases.
Our recent paper provides guidelines to achieve the true maximum solubility in compounds.

Yes, skutterudite. Compositionally we prefer CoSb3.
