“…Tin selenide is a promising material for thermoelectric applications 134 , and was recently drawn in a borosilicate cladding 135 , followed by CO 2 laser annealing to form single crystalline material 10 . In these experiments, the initial composition of the core was SnSe, and fibres were drawn at 1100 °C.…”

Novel core fibers have a wide range of applications in optics, as sources, detectors and nonlinear response media. Optoelectronic, and even electronic device applications are now possible, due to the introduction of methods for drawing fibres with a semiconductor core. This review examines progress in the development of glass-clad, crystalline core fibres, with an emphasis on semiconducting cores. The underlying materials science and the importance of post-processing techniques for recrystallization and purification are examined, with achievements and future prospects tied to the phase diagrams of the core materials.

“…Then the blank is pulled at a suitable speed to form a viscous flow, which can finally be elongated into fibers with micron-scale diameters. Yang et al prepared a Sn-Se alloy core borosilicate glass-clad fiber with a core diameter of 94 µm by thermal co-drawing [ 46 ]. The TE fiber core was composed of SnSe polycrystalline grains and had a high Seebeck coefficient of −151 µV K −1 at 300 K. They used the same method to fabricate bismuth selenide fibers with a diameter of 50 μm [ 47 ].…”

“…Thermoelectric parameters were measured at 370 K and exhibited a ZT value of 0.156 for the 130 nm diameter nanowire [ 19 ]. Furthermore, a SnSe core glass cladding fiber with ~94 μm core and ~220 μm cladding was prepared by a molten core drawing method, as shown in Figure 2 b [ 35 ]. This method has potential to produce the next generation of low-cost, high-yield, one-dimensional TE fibers [ 35 ].…”

With the rapid development of wearable electronics, looking for flexible and wearable generators as their self-power systems has proved an extensive task. Fiber-based thermoelectric generators (FTEGs) are promising candidates for these self-powered systems that collect energy from the surrounding environment or human body to sustain wearable electronics. In this work, we overview performances and device structures of state-of-the-art fiber-based thermoelectric materials, including inorganic fibers (e.g., carbon fibers, oxide fibers, and semiconductor fibers), organic fibers, and hybrid fibers. Moreover, potential applications for related thermoelectric devices are discussed, and future developments in fiber-based thermoelectric materials are also briefly expected.
