Mechanical Stiffness and Dissipation in Ultrananocrystalline Diamond Films
Tetragonal sp3-bonded diamond has the highest known atomic density. The nature of the bond and its high density enable diamond to have superior physical properties such as the highest Young’s modulus and acoustic velocity of all materials, and excellent tribological properties. Recently, conformal …

Synthesis and characterisation of DLC and diamond films for gas sensing applications
Over the last decade diamond like carbon (DLC) and diamond films have been extensively studied. These studies were only focused on the synthesis and characterization of this material. DLC films have some unique properties as a semiconductor such as a high elastic modulus, high mechanical hardness, …

Filament-Assisted Chemical Vapor Deposition of Diamond and Its Mechanism
Diamond films were deposited on various substrates by filament-assisted chemical vapor deposition (FACVD). Different experimental conditions were employed to determine the effects of parameters such as filament temperature, methane concentration in the starting gas, and substrate temperature on …

Highly Conductive Ultrananocrystalline Diamond Thin Films via Nitrogen Incorporation
Diamond has many superlative properties that make it an ideal candidate for a number of different mechanical and electronic applications. One of the biggest limiting factors has been the lack of n-type diamond films with suitable conductivity. This work demonstrates a method to fabricate a highly …

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. …

Characterizing growth conditions in chlorine-activated diamond chemical vapor deposition
… chemical vapor deposition (CACVD) of thin diamond films. Numerical modelling at various levels of sophistication results in good trend and reasonable magnitude agreement between numerical and experimental data. Modelling suggests a low substrate temperature diamond growth mechanism by …

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 …

Investigation of stagnation-flow diamond-forming flames using advanced laser diagnostics
… in atmospheric-pressure, stagnation-flow diamond-forming flames. In these flames, a rich acetylene/oxygen/hydrogen mixture accelerates through a nozzle and impinges on a water-cooled molybdenum substrate, stabilizing a flat-flame approximately 1 mm below the substrate. A thin, …

Luminescent nanofluids based on perovskite materials and nanodiamonds
… perovskite (ABX3) quantum dots (QDs) and nanodiamonds stand out. However, the emission wavelength of perovskite QDs typically lies within the visible range, and the potential for using nitrogen-vacancy (NV-) and silicon-vacancy (SiV-) centres in nanodiamonds for temperature sensing remains …
