Using galvanostatic pulse deposition, we studied the factors influencing the quality of electroformed Bi1–xSbx nanowires with respect to composition, crystallinity, and preferred orientation for high thermoelectric performance. Two nonaqueous baths

Achieving control of crystalline quality is a key barrier to developing thermoelectric (TE) nanowires. We show that the structural properties of free-standing Bi2(Te.97Se.03)3 nanowire arrays on substrates can be improved by postdeposition annealing.

Electrodeposition is a promising low-cost method to fabricate nanostructured thermoelectric thin films such as Sb 2 Te 3 . However, electrodeposition of crystalline Sb 2 Te 3 without the need for additional processing and with good compositional cont

We report the fabrication of Bi2Te3 nanowires with diameters as small as 15 nm, which is comparable to the size theoretically estimated for the onset of improvement of the thermoelectric figure of merit ZT by quantum-size effects. The versatility of

Thin film Bi2Te3/Sb2Te3 multilayers are thought to possess a high thermoelectric figure of merit. Our work describes how multilayers can be fabricated using electrodeposition, an inexpensive and scalable synthesis route. We address the challenge of s

Syntaxial growth of Mn11Ge8/Ge nanowire heterostructures was carried out using a vapor–solid–solid (VSS) growth process, and transmission electron microscopy imaging and selected-area electron diffraction were used to study the structure, orienta

Nanostructuring of thermoelectric materials is expected to enhance thermoelectric properties by reducing the thermal conductivity and improving the power factor from that of homogeneous bulk materials. In multiphase, nanostructured thermoelectric mat
