In this study, a novel Al doping method was used to grow p-type SiC. p-Type 4H-SiC crystals were grown by a physical vapor transport (PVT) … WebThe foundation for our p-MOSFET is a silicon-face, p-type 4H-SiC substrate with the thickness of 350 mm and resistivity of 2 Ωcm. On this we deposit a 5 mm-thick drift layer with a doping concentration of 1.6à—10 16 cm -3 .
WebJun 3, 2024 · During the many years of work with the characterization of SiC, we have a large collection of materials including HPSI 4H-SiC substrates from different suppliers as well as n-type and p-type 4H-SiC irradiated by 2-, 2.5-, or 3-MeV electrons with the fluence covering a wide range of 10 14 –10 19 cm −2. WebBoth n- and p-type SiC of different doping levels were electrochemically etched by HF. The etch rate (up to 1.5 μm/min) and the surface morphology of p-type 6H-SiC were sensitive to the applied voltage and the HF concentration. The electrochemical valence of 6.3 ± 0.5 elementary charge per SiC molecule was determined. At p-n junctions (p-type layer on a n …
