Awschalom and co-authors also describe that they can take a page from the modern electronics industry’s playbook to drastically improve their quantum states.
Silicon carbide, due to the close proximity of silicon and carbide on the periodic table, is a highly covalent material that forms tetrahedra that are centered around either carbon or silicon atoms. These tetrahedra form a close-packed structure with half of the tetrahedral sites filled, and occur primarily in the α-SiC and β-SiC phases.
Silicon Carbide (SiC) is a compound semiconductor material. While there are some types of crystalline structures including 3C-SiC, 6H-SiC and 4H-SiC, it is considered that 4H-SiC is the most promising material as a substrate of power devices. 4H-SiC has a wide band gap, a high breakdown field and a high thermal conductivity compared to silicon.
