“…[16][17][18][19] A method for deposition of diamond microcrystals using a jet printer has also been developed. 20 In this article laser acceleration allows the nanodiamond particles to be positioned and ordered on the surface and to penetrate deep in to the Ag layer. Strong interaction between the nanodiamond and Ag can be achieved, which allows us to observe surface-enhanced Raman scattering.…”

Surface-enhanced Raman scattering was applied to study the nanodiamond with particles’ sizes 100 and 5 nm, positioned on silver (Ag) substrate using high focused laser beam acceleration method. The nanodiamond particles suspended in distilled water were accelerated by a near infrared laser beam and attached to an Ag foil serving as the target. This allows the nanodiamond particles to be ordered, positioned, and to penetrate deep into Ag. The nanodiamond–Ag surface structure after nanoparticles∕laser beam treatment was analyzed using micro-Raman spectroscopy and scanning electron microscopy. Strong interaction between the nanodiamond and Ag surface can be achieved, which allows us to observe surface-enhanced Raman scattering (SERS). The most significant enhancement observed for carbon was trans-polyacetylene bands in addition to the D and G bands. The enhancement can achieve orders in magnitude both for 100 and 5 nm nanodiamonds. The selective enhancement of some composite band intensity, a characteristic feature of SERS referred to as the blinking effect, was also observed.

“…Describing the main characteristics of a nanodiamond suspension (particle shape, surface chemistry 176 and charge, size distribution, solvent nature), we underlined the relevance of the colloidal chemistry on the seeding quality. The stability of the diamond nanoparticles under plasma conditions was also mentioned.…”

“…Fox et al developed a technique based on water ink containing nanodiamonds. 176 By standard ink jet technology, local seeding has been realized by Fox et al on glass, silicon, copper and fused quartz (Figure 10.16) with micrometric patterns. An alternative at the nanometric scale has been recently proposed by Zhuang et al, who used microcontact printing with a nanodiamond-based ink.…”

The controlled growth of ultra-thin diamond layers on a diversity of substrates is a major challenge for many technological applications (heat spreaders, electromechanical systems, etc.). This explains the huge effort produced during the last two decades to master the early stages of diamond formation. Two main pathways have been investigated in the literature. The nucleation pathway aims to produce diamond nuclei, i.e., the smallest thermodynamically stable diamond islands, at the substrate surface. This is mainly performed by in situ treatments preceding diamond chemical vapor deposition (CVD) growth, such as bias enhanced nucleation (BEN). The second approach consists of skipping the nucleation stage by covering, ex situ, the substrate with diamond nanoparticles, which act as seeds for diamond CVD growth. The present chapter is a review of these pathways. Their respective benefits and drawbacks are discussed. Finally, these two approaches appear very complementary. Seeding allows the growth of ultra-thin diamond layers on large non-conductive substrates with micrometric patterns. On the other hand, the BEN in situ nucleation treatment remains the favored technique to achieve well-adherent diamond films and diamond heteroepitaxy.

“…However, the realization of various diamond-based devices depends on the approaches of diamond patterning. Currently a great number of efforts have been made to obtain patterned diamond [4][5][6][7][8][9]. One key challenge to diamond patterning on non-diamond materials is selective diamond growth for the fabrication of diamond-based devices.…”

Seed-Free Growth of Diamond Patterns on Femtosecond Laser Processed Silicon Substrates

et al. 2013

Due to its outstanding properties, diamond is considered as an ideal material for mechanical and electric applications at high temperatures, voltages, radiation, etc. It is known that femtosecond lasers exhibit extremely high precision and minimized thermal effect in material processing. In this study, a seed-free diamond pattern growth method was developed by patterning silicon substrates using a femtosecond laser before diamond deposition through laserassisted combustion flame synthesis. The resolution of the diamond patterns reaches micro scales. Peak position, full width at half maximum (FWHM), and diamond quality parameter were calculated from Raman spectra. The mechanism of the seed-free diamond growth based on the femtosecond laser patterning was discussed. The influence of substrates surface roughness on the diamond nucleation and subsequent growth was studied, indicating that the nucleation density is proportional to the surface roughness.
