“…The corresponding SAED pattern marked in Figure 4B,E reveals the polycrystalline nature of the InSb O-NW and InSb P-NW. The obtained lattice fringes of 0.33 and 0.36 nm correspond to the (200) and (111) planes for InSb O-NW and 0.24 and 0.20 nm oriented in (220) and (311) planes for P-NW explicit the zinc-blende crystal phase[30,31]. The obtained results confirm that the growth of InSb NWs was preferentially oriented along the zone axis (Figure4C,F).The crystalline structure and characteristics of the Insb NWs synthesized using the AAO template-assisted VDC process were scrutinized using X-ray diffraction analysis.…”

“…The AAO template-assisted VDC approach performs admirably in synthesizing 1D NWs with exceptional purity and homogeneity. The high pressure and temperature utilized in the VDC approach can intensely control material diffusion on the AAO channel, which directly impacts porous deterioration and defect-free NW growth [30]. On the other hand, the VDC approach has been understudied and lacks solid empirical proof for parametric control in NWs tailoring.…”

Herein, we demonstrate a facile technique for the fabrication of one-dimensional indium antimonide (InSb) nanowires using anodic aluminium oxide (AAO) template-assisted vacuum die-casting method. The filling mechanism of the vacuum die-casting process is investigated on varying AAO pore structures through different electrolytes. It is found that the anodizing electrolytes play a vital role in nanowire growth and structure formation. The as-obtained InSb nanowires from the dissolution process show a degree of high crystallinity, homogeneity, and uniformity throughout their structure. The TEM and XRD results elucidated the InSb zinc-blende crystal structure and preferential orientation along the c-axis direction. The thermoelectric characteristics of InSb nanowires were measured with a four-electrode system, and their resistivity, Seebeck coefficient, power factor, thermal conductivity, and ZT have been evaluated. Further, surface-modified nanowires using the reactive-ion etching technique showed a 50% increase in thermoelectric performance.

“…Compared to empty nanoscale channels within a porous 1‐D material, building‐up from individual nanowires instead avails a larger variety of compositions. Moreover, nanowires can freely be arranged in many more configurations, which also fortuitously provides a route in‐turn towards more sophisticated porous nanostructured materials during the preparation of templates [66] …”

Nanowire‐like materials exhibit distinctive properties comprising optical polarisation, waveguiding, and hydrophobic channelling, amongst many other useful phenomena. Such 1‐D derived anisotropy can be further enhanced by arranging many similar nanowires into a coherent matrix, known as an array superstructure. Manufacture of nanowire arrays can be scaled‐up considerably through judicious use of gas‐phase methods. Historically, the gas‐phase approach however has been extensively used for the bulk and rapid synthesis of isotropic 0‐D nanomaterials such as carbon black and silica. The primary goal of this review is to document recent developments, applications, and capabilities in gas‐phase synthesis methods of nanowire arrays. Secondly, we elucidate the design and use of the gas‐phase synthesis approach; and finally, remaining challenges and needs are addressed to advance this field.
