Contact reaction of silicon carbide with fused copper

1. We have studied the contact reaction and wetting of single crystals and polycrystalline silicon carbide by liquid copper. 2. It is shown that pure copper decomposes silicon carbide to form a Cu-Si alloy and graphite. 3. The presence of small amounts of silicon in copper suppresses the reaction of copper with silicon carbide. 4. We have verified our hypothesis that the resistance to copper

Home - Power Electronics Forum

In the recent years silicon carbide (SiC) Schottky diodes has been established as state-of-the-art rectifier technology in power electronics. However, SiC rectifiers are usually used at 650V and beyond and they come with a premium price compared to silicon-based solutions.

Graphene - Wikipedia

Graphene (/ ˈ ɡ r æ f iː n /) is an allotrope of carbon consisting of a single layer of atoms arranged in a two-dimensional honeyco lattice. The name is a portmanteau of "graphite" and the suffix -ene, reflecting the fact that the graphite allotrope of carbon consists of stacked graphene layers.. Each atom in a graphene sheet is connected to its three nearest neighbors by a σ-bond, and
