“…CVD and solvothermal synthesis can produce TI nanoplates in high yield with relatively high quality and some degree of controllability at the same time. 42,43,[69][70][71][72][73][74][75][76][77] It is to be noted that CVD has an advantage over solvothermal synthesis in sample quality for its relative clean reaction system. CVD and solvothermal synthesis play more significant roles in preparing 1D TI materials such as nanowires, nanoribbons, and nanotubes.…”

Topological insulators demonstrate tremendous potential in fields of electronics and magnetism for their unique boundary states that are topologically protected against backscattering at non-magnetic impurities and defects. Intriguingly, most topological insulators are also excellent thermoelectric materials, since topological insulator and thermoelectric compounds share similar material features, such as heavy elements and narrow band gaps. While the influence of topological insulator boundary states has long been neglected in early thermoelectric research, recently this neglected issue has attracted intensive research efforts. A lot of theoretical and experimental investigations have emerged to explore the contribution of topological insulator boundary states to thermoelectricity. Here, we will review the most updated theoretical and experimental progresses, trying to offer a comprehensive understanding on the relation between thermoelectric properties and topological nature. Special emphasis will be laid on the potential of topological states for improving thermoelectric properties, to pave a new way of realizing high-performance thermoelectric devices.

1 Introduction Topological insulators (TIs) are recently discovered quantum materials that are insulating in the bulk, but conductive on the surface [1][2][3]. Gapless surface states in TIs originate from strong spin-orbit coupling in the bulk, and exhibit special electronic property of spinmomentum locking due to time reversal symmetry. The exotic electronic nature of the TI surface states has garnered intense interests in this new class of materials and can be used to study several fundamental physical phenomena inaccessible in ordinary materials. The spinmomentum locking property of the TI surface states will undoubtedly be useful for a broad range of future electronic applications such as dissipationless transport, spintronics, and quantum computing.In this review, we follow the recent experimental research progress in TI nanostructures, and discuss various nanomaterial synthesis methods and notable transport measurements. Also, current materials challenges that hinder the easy access and control of the TI surface states are identified and unique solutions that TI nanostructures can provide to overcome these challenges are suggested.

Nano-sized antimony telluride is of much interest for improving the thermoelectric figure of merit. In the present work, organic-assisted antimony telluride nanorods were successfully fabricated by a simple hydrothermal method. The products were characterized by means of X-ray diffraction, scanning electron microscope, and transmission electron microscope. The results show that the typical antimony telluride synthesized by co-precipitation reductive route is rodlike in shape with about 35 nm in thickness and 300 nm in edge length.
