4H Silicon Carbide (SiC) Substrates to Fabricate Integrated Photonic Components and Devices
A Electrical and Computer Engineering Ph.D candidate requested the following quote:
I want to use the silicon carbide for integrated photonic components and devices such as waveguides and ring resonators. Therefore, I am quite interested in the 4H silicon carbide on insulator (4H-SiCOI) wafers, which has 4H-SiC thin films on top of the SiO2 on Si carrier wafers. I have read that one approach to get this kind of wafers is to bond the 4H-SiC wafers with the SiO2 on Si carrier wafers and then to grind the 4H-SiC wafers down to the thickness of several microns. I wonder whether you can provide such a kind of wafers.
The diameter can either be 4-inch or 2-inch based on your inventory. The type of 4H-SiC wafer should be insulating with 0-deg off axis. The thermally grown SiO2 should at least be 1um thick with good surface conditions. And if possible, please quote for only 1 wafer.

Some of SiC Wafers Current and Future Uses
Unmanned Aerial Vehicles (UAV)
Future SiC applications include smaller speed controllers for the 
remote-control aircraft and UAV hobbyists. These stronger, smaller speed controllers can work with at higher voltage and currents in compact spaces. For UAV drone racing SiC power devices hold great promise for their increased performance, maximized speed and increased endurance.
Formula E Racing Implementing Silicon Carbide Based Power Devices
For battery operated UAVs and electric vehicles SiC’s low power loss, and reduced weight equates to longer battery life and more efficient operations. Estimates from electric formula-one racing see a 30% increase in power inverters electric performanc
Increased Efficiency in Smaller Package Using Silicon Carbide Schottky Diodes
Unliked Silicon-based diodes, Silicon Carbide Schottky Diodes have a smaller capacitive charge (Qc). This reduces switching loss, thus enabling high-speed switching operation. SiC devices are aslo more stable at all temperatures resulting in contstant perfomance that is much better than their Silicon-based equivalent.
