Experimental and Ab Initio Study of Cu2SnS3 (CTS) Polymorphs for Thermoelectric Applications
Published in The Journal of Physical Chemistry C
Cu2SnS3 (CTS) is a medium-temperature, ecofriendly, p-type thermoelectric material known for phonon-glass-electron-crystal characteristic. In the present work, ordered and disordered CTS samples were prepared from elemental powders, and their electronic and vibrational properties were systematically investigated by experimental methods and ab initi...
Effects of Grain Size on the Thermoelectric Properties of Cu2SnS3: An Experimental and First-Principles Study
Published in ACS Applied Energy Materials
Cu–Sn-based sulfides are earth-abundant and nontoxic compounds of special interest for low-cost energy harvesting applications. In the present work, we have investigated the effect of grain size on the thermoelectric properties of Cu2SnS3 (CTS). Three dense CTS samples with nanometric grains were produced by mechanical alloying combined with spark ...
