NMR investigations on topological quantum materials

There are different types of topological materials have been studied in this project, including topological nodal-line semimetal ZrSi(Te, Se, S), topological semimetal ZrTe2 and topological insulator/semimetal ZrTe5.

NMR investigations on advanced thermoelectric materials

Several different types of thermoelectric materials have been studied, including half-Heuslers, skutterudites and tetrahedrites. Half-Heusler, or semi-Heusler, compounds (space group F43m) comprise a relatively large family of materials with diverse physical properties and applications. Functional materials based on these compounds include thermoelectric semiconductors, piezoelectric semiconductors, optoelectronic semiconductors, and topological insulators.

Machine learning approach to FINEMET-type soft magnetic alloys design

This work focuses on new soft magnetic materials design. We take advantage of materials informatics to build statistical model which is able to link processing procedures and materials properties together. Fe-based nanocrystalline alloys is main type of material to be studied. Data set is extracted from experimental results of publications.
