The plasticity of diamond
Aspects of the crystal structure of diamond, and its associated defects, have been considered with reference to the effect such characteristics might have on its mechanical properties. Also, established resolved shear stress models, which account for anisotropy in conventional Knoop indentation …

Diamond seeding process for the heterogenous integration of high quality diamond on semiconductors
Diamond thin films grown by chemical vapor deposition (CVD) have a wide band gap, high hardness, chemical inertness, and high thermal conductivity, making them an attractive material for a wide range of applications. Due to high surface energy and low sticking probability of diamond, it is …

Characterization of Diamond-Semiconductor Interfaces
The extremely high thermal conductivity of diamond thin films makes them an ideal candidate for heat spreaders that can be integrated with electronic devices. By more effectively dissipating the heat generated during operation device dimensions can be shrunk increasing yield, performance losses due …

Nonlinear Cavity Optomechanics in Diamond
Diamond has been proven to be a particularly useful material for implementing quantum technologies due to the various defects known as color centers. These color centers can be coupled to both photons and phonons; therefore, they enable the realization of a hybrid quantum system that consists of …

Electrodeposition of Diamond-like Carbon Films
Electrodeposition of diamond-like carbon (DLC) films was studied on different substrates using two different electrochemical methods. The first electrochemical method using a three-electrode system was studied to successfully deposit hydrogenated DLC films on Nickel, Copper and Brass substrates. …

Synthetic industrial diamond : a technological outlook
Synthetic diamonds are successfully substituting for natural diamonds in the area of industrial application. Synthetic diamonds increased their market share from 10% in 1960 to 50% in 1968 and to 90% in 1994. The success of synthetic diamonds may be ascribed largely to technological advance in the …

Rock Drilling with impregnated diamond microbits
… drill a variety of rock types with impregnated diamond microbits. The rocks, selected to represent a wide range of properties, were characterised by optical petrography and by the measurement of uniaxial compressive strength and relative abrasion resistance. A computer controlled electronic data …

Lead-related quantum emitters in diamond
… emission from Pb-related color centers in diamond following ion implantation and high temperature vacuum annealing. First-principles calculations predict a negatively-charged Pb-vacancy center in a split-vacancy configuration, with a zero-phonon transition around 2.3 eV. Cryogenic …
