On 8th July 2021 Mila has successfully defended her thesis in front of committee of GIeßen University. Her thesis title “Influence of the Composition of p-type Mg2X (X=Si, Ge, and Sn) on Thermoelectric Properties and Electronic Band Structure lays out promising candidates of p-type materials for thermoelectric, which their efficiency has been so far below the n-type materials. This finding is recommendable as one of promising p-type materials for thermoelectric.
