“…Trejo and coworkers reported the optical phonons and Raman-scattering properties of DNWs by using a local bond polarization model based on the displacement-displacement Green's function and the Born potential [70]. Further, they have also studied the electronic band structure of DNWs through a semiempirical tight-binding approach and compared with density functional theory (DFT) studies.…”

Due to the superior hardness and Young's modulus, biocompatibility, optical and fluorescence nanodiamond seems to be outstanding among carbon nanomaterials. In this footpath, the development of diamond nanowires (DNWs) is known to be a significantly innovative field due to their diverse applications such as sensors, semiconductors, and electrochemical utilities. Compared to carbon nanotubes, DNWs theoretically have energetic and mechanically viable structures. However, DNW synthesis in a reproducible way is still a challenging task. In fact, most of the DNWs can be successfully synthesized by chemical vapor deposition (CVD) and reactive-ion etching (RIE) techniques. By contrast, solution-based DNW synthesis has also emerged recently. A detailed study on DNW structures may help the emerging researchers to direct toward diverse applications. In this chapter, we comprehensively presented the up-to-date applications of DNWs along with their synthesis, structures and properties.

“…[149,150] Recently, a local bondpolarization model based on Greens displacement-displacement function and the Born potential were applied by Trejo et al to study the confined optical phonons and Raman scattering of diamond nanowires (DNWs). [151] The electronic band structure of DNWs were also investigated by means of a semiempirical tight-binding (TB) approach and compared with density functional theory (DFT) with local density approximation (LDA). The results show that the highestfrequency Raman peak shifts to lower frequencies as the nanowire width increases, as a result of phonon confinement, in accordance with the experimental data.…”

C(sp(3) )C-bonded diamond nanowires are wide band gap semiconductors that exhibit a combination of superior properties such as negative electron affinity, chemical inertness, high Young's modulus, the highest hardness, and room-temperature thermal conductivity. The creation of 1D diamond nanowires with their giant surface-to-volume ratio enhancements makes it possible to control and enhance the fundamental properties of diamond. Although theoretical comparisons with carbon nanotubes have shown that diamond nanowires are energetically and mechanically viable structures, reproducibly synthesizing the crystalline diamond nanowires has remained challenging. We present a comprehensive, up-to-date review of diamond nanowires, including a discussion of their synthesis along with their structures, properties, and applications.

“…It is well-known that phonon properties play an important role in the considered systems because of their significance for the analysis of various physical processes, such as, charge and thermal transport, and optical transitions, hence phonon band structures of Si and Ge nanowires have been investigated through DFPT (density functional perturbation theory) [124,125]. Recently, A local bond-polarization model based on the displacement-displacement Green's function and the Born potential are applied to study the confined optical phonons and Raman scattering of diamond nanowires (DNWs) by Trejo et al [126]. Also, the electronic band structure of DNWs are investigated by means of a semi-empirical tight binding (TB) approach and compared with density functional theory (DFT) within local density approximation (LDA).…”

Diamond is a wide band gap semiconductor exhibiting a combination of superior properties, such as negative electron affinity, chemical inertness, high Young's modulus, the highest hardness and room-temperature thermal conductivity, etc. It is possible to control and enhance the fundamental properties of diamond by fabricating 1D diamond nanowires, due to the giant surface-to-volume ratio enhancements of 1D nanowires. Although theoretical comparisons with carbon nanotubes have shown that diamond nanowires are energetically and mechanically viable structures, reproducibly synthesizing the crystalline diamond nanowires has remained challenging. In this chapter, we present a comprehensive, up-to-date review for the diamond nanowires, wherein we will give a discussing for their synthesis along with their structures, properties and applications.
