Nanoscale materials with inter-correlation characteristics are fundamental for developing high performance devices and applications. Hence theoretical research into unprecedented two dimensional (2D) materials is crucial for understanding especially when piezoelectricity...
Thermoelectric materials have an important role in electronic chips due to their capability of heat and electricity interconversion. Here we investigated thermoelectric properties of Zn3As2 and ZnSb by using density functional theory combined with the Boltzmann transport equation. We evaluated the well‐known thermoelectric figure of merit (ZT) of both materials and found a maximum ZT of 0.09 and 0.27 for Zn3As2 and ZnSb at 200°C and 1000°C, respectively. While investigating the electronic properties, we found that Zn3As2 has a direct band‐gap at the Γ‐point of 1.01 eV, while ZnSb has an indirect bandgap of 0.65 eV. Both materials exhibited high optical absorption and reflectivity in the visible and UV regions, which suggest that these materials are beneficial in photovoltaic cells, along with thermoelectric applications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
