The Use of Microwave Radiation for Synthesis of a …
A new composite ceramic material based on silicon carbide and complex oxide is synthesized by the microwave radiation method at a frequency of 2450 MHz. The material is characterized by loss tangent tan δ = 0.072 – 0.075 and has prospective appliions in radio and microwave technology. The material, owing to its radio-absorbing properties, can be used to fabrie heaters for microwave
X-Fab Rides IPO to New Growth | Applied Materials
But a legacy 150mm (6-inch) wafer fab in Lubbock, Texas, is making its own mark: reinventing itself by moving into the forefront of silicon carbide (SiC) power ICs. With its origins in the 1970s memory chip production era of Texas Instruments, X-FAB acquired the fab from TI in 1999 and converted it into an analog/mixed-signal facility, producing largely automotive-use ICs.
Measurement of Dielectric Material Properties
The loss tangent is also called by terms such as tangent loss, dissipation factor or loss factor. Measurement Methods Rohde & Schwarz < Measurement of Material Dielectric Properties> 4 The complex permeability also consists of a

In this paper, we present a study of bright single-photon emitters in cubic silicon carbide (3C-SiC) emitting in the telecom range. We find that these emitters are photostable and bright at room
Microwave losses of undoped n-type silicon and …
Meanwhile, the loss tangent of pristine 4H-SiC appeared to be very high with a value of 0.01 at 10 K at 8.6 GHz, which is 4000 times higher than that of our undoped Si. When the pristine 4H-SiC was irradiated with thermal neutrons, the loss tangent was enhanced by seven times due to the significantly reduced electrical resistivity.
