A pure diamond is made entirely of carbon. At an atomic level, a diamond is simply a lattice of repeating carbon atoms with covalent bonds to their nearest four carbon neighbours. However, sometimes one of the carbons is replaced in the lattice by a non-carbon element known as a dopant. When a dopant is introduced to a diamond, however, it may be a...
One of the challenges with using diamonds for technological applications is the price. Diamond mining is a tightly controlled market, and while natural gemstones may be sought after for their aesthetics, the predictability and customisability of lab-grown diamonds are highly appealing for scientific and engineering applications. Luckily, scientists...
One of the electronics industry’s big drives has been finding ways to make components smaller. Moore’s Law, which predicts that the number of transistor components that will fit on a chip will double every two years, has overseen the explosive growth in computing power that has marked the last 60 years. Consequently, transistors – the electrical co...
With her success at improving the performance and lifetime of high-power LED components, Mendes has also been focusing on another area of device development for a type of transistor known as a high electron mobility transistor (HEMT). HEMTs are a type of transistor usually fabricated from semiconductor materials like gallium nitride (GaN). What mak...
Despite its excellent performance, one of the biggest challenges of incorporating diamond into daily-life devices is that this increases the fabrication cost – going against the grain of the current practice of inbuilt obsolesce. However, there are applications where the lifetime of electronic components should be as long as possible – and as low w...
Feb 4, 2023 · Diamond films have considerable applications for heat sink and high-power chips such as high-electron-mobility transistors and quantum devices where unique electronic or quantum properties,...

Apr 24, 2024 · Here we describe the growth of diamond crystals and polycrystalline diamond films with no seed particles using liquid metal but at 1 atm pressure and at 1,025 °C, breaking this pattern.
Diamond films have been considered as ideal candidates for protective coatings on bioimplants, as bioimplants themselves or as a guide for neural differentiation, because of their excellent mechanical properties, functional amenability, biocompatibility, and unique nanostructures.
Jul 30, 1999 · In this review we will briefly discuss diamond properties, diamond applications, and diamond growth by chemical vapor deposition in 2 Properties and applications of diamond and diamond films, 3 CVD processes for diamond growth.
Many thin diamond films are formed by chemical vapor deposition (CVD). Imperfections in the films such as graphite inclusions and lattice defects that can create intrinsic stress often arise during CVD.
