Gallium nitride (GaN)-based high electron mobility transistors (HEMTs) are a type of field-effect transistors (FETs) designed to operate at very high frequencies with low noise. As such, they have ...

Mars just gave up one of its oldest secrets — and it took a decade, a spacecraft, and a cosmic cannonball to catch it in the act. For the first time, NASA’s MAVEN mission has directly observed a ...

Thin films play a crucial role in the fabrication of several components and devices, such as protective coatings, integrated circuits, solar cells, and optical ...

Sputtering Technique Sputtering is a process wherein a controlled gas, typically chemically inert argon, is introduced into a vacuum chamber and then a cathode is electrically energized to generate a ...

Sputtering targets are the source materials for the preparation of sputtered thin films. In particular, high-purity sputtering targets are used in the physical vapor deposition (PVD) process for the ...

This video shows SemicoreEquipment's sputtering manufacturing process. This process starts when a substrate to be coated is placed in a vacuum chamber containing an inert gas. The negative charge is ...

The word “sputtering” may evoke images of a car engine choking before it fails, but in the high-tech world of advanced coatings, it's a high-speed, high-volume process where superfast ions hit a metal ...

Researchers at University of Tsukuba have developed a technology for real-time estimation of the valence state and growth rate of iron oxide thin films during their formation. This novel technology ...

Mars changed from a blue world with water to a red desert because its atmosphere escaped into space over billions of years.
