The fourth in a series of workshops was held at NIST on March 4-5, 1996 to discuss, in depth. specific topics deemed important to the characterization of diamond films made by chemical vapor deposition (CVD diamond) and to address the need for standards in diamond technology. There were 28 registered participants at the workshop. We focussed on two technical topics for discussion: adhesion of C...

We demonstrate the construction of diamond photonic crystal structures by the translation of a multi-beam interference pattern. Using phase shift of each beam, the double-exposed interference patterns can be aligned in the [111] direction for a face-centered cubic (FCC) and [210] direction for a body-centered cubic (BCC), respectively, producing diamond D from FCC and BCC-diamond like structure...

The surface of hydrogen-terminated diamond resembles a solid hydrocarbon substrate. Interestingly, the C-H bonds on the diamond surface are not as unreactive as that of saturated hydrocarbon molecules owing to its unique surface electronic properties. The invention of C-H bond activation and C-C coupling reactions on the diamond surface allows chemists to develop powerful chemical transistors, ...

a r t i c l e i n f o The amorphization and graphitization of single-crystal diamond by ion implantation were explored using transmission electron microscopy (TEM). The effect of ion implantation and annealing on the microstructure was studied in (100) diamond substrates Si + implanted at 1 MeV. At a dose of 1 × 10 15 cm − 2, implants done at 77 K showed a damage layer that evolves into amorpho...

342 NATURE | VOL 399 | 27 MAY 1999 | www.nature.com A micro-Raman spectrometer was used for the further characterization of the deposited diamond. A laser beam of 1-mm spot size was focused onto the crystallites. Figure 3 shows the resulting Raman spectrum: it exhibits a first-order diamond peak centred at 1,332.8 cm. The high intensity of the diamond peak, its small full-width at half-maximum ...

The impressively low friction and wear of diamond in humid environments is debated to originate from either the stability of the passivated diamond surface or sliding-induced graphitization/rehybridization of carbon. We find ultralow friction and wear for ultrananocrystalline diamond surfaces even in dry environments, and observe negligible rehybridization except for a modest, submonolayer amou...

Microand nanomachining of diamond using focused ion beam (FIB) continues to generate interest in applications such as diamond anvil cells, photonic devices, micro-cantilevers and tools for imprinting applications [1,2]. However, the milling rate of diamond by FIB is approximate 4X slower when compared to silicon using 30 kV Ga FIB [3]. Recent instrumentation using PFIB technology and Xe ions of...

Silicon crystallizes in the diamond-cubic phase and shows only a weak emission at 1.1 eV. Diamond-hexagonal silicon however has an indirect bandgap at 1.5 eV and has therefore potential for application in opto-electronic devices. Here we discuss a method based on advanced silicon device processing to form diamond-hexagonal silicon nano-ribbons. With an appropriate temperature anneal applied to ...
