CdTe nanowires with controlled composition were cathodically electrodeposited using track-etched polycarbonate membrane as scaffolds and their material and electrical properties were systematically investigated. As-deposited CdTe nanowires show nanocrystalline cubic phase structures with grain sizes of up to 60 nm. The dark-field images of nanowires reveal that the crystallinity of nanowires wa...

Recently, Cu2-δS and Cu2-δSe were reported to have an ultralow thermal conductivity and high thermoelectric figure of merit zT. Thus, as a member of the copper chalcogenide group, Cu2-δTe is expected to possess superior zTs because Te is less ionic and heavy. However, the zT value is low in the Cu2Te sintered using spark plasma sintering, which is typically used to fabricate high-density bulk s...

Hafnium and zirconium are commonly thought to be very similar in chemistry. However, they are surprisingly dissimilar in the chemistry of metal-rich chalcogenides. For instance, Hf2S [1] and Hf2Se [2] are comprised of hexagonal closepacked double metal atom layers spaced by sulfur or selenium while both Zr2S [3] and Zr2Se [4] crystallize in a Ta2P-type structure [5]. Zr2Te [6] and Hf2Te [7] ado...

Antimony telluride (Sb2Te3) based alloys are well-known as promising thermoelectric materials for near-room temperature applications. In this work, we present a simple and cost effective electrodeposition approach developing CuSbTe...
