Schottky diodes Schottky diodes are constructed of a metal-to-N junction rather than a P-N semiconductor junction.Also known as hot-carrier diodes, Schottky diodes are characterized by fast switching times (low reverse-recovery time), low forward voltage drop (typically 0.25 to 0.4 volts for a metal-silicon junction), and low junction capacitance.

0 Cordless Sanders of 2019 | Video Review

The most common are garnet, aluminum oxide, silicon carbide, and ceramic. Garnet wears out the quickest, but is capable of producing the smoothest surface. This makes it best when performing the final stages of sanding. Aluminum oxide has a self-renewing

Vertical GaN Devices: The Next Level of Power Electronics …

Silicon carbide (SiC) is another alternative to silicon, but GaN generally has more attractive fundamental material properties. Current GaN devices are made on hybrid substrates: thin layers of GaN on silicon or silicon carbide, creating GaN-on-Si or GaN-on-SiC high-electron-mobility transistor (HEMT) structures ( Figure 3 ).

HIP - Hot Isostatic Pressing - Bodycote

For example, an aluminium alloy matrix with a high proportion of silicon carbide ceramic particles may be compacted to full density by the HIP process to give a very light and stiff material. Many precision airframe castings from alloys such as titanium, aluminium and steel are HIPed to ensure integrity, optimise mechanical properties and improve fatigue life.
