Incorporation of boron and vanadium during PVT …

1/11/2001· To obtain semi-insulating SiC by vanadium and boron co-doping during PVT growth, a detailed understanding of the dopant (B,V) incorporation is required. Crystal growth of 1.4′′ 6H-SiC on either Si or C face, doped with boron or vanadium, respectively, was performed. For reference purposes, also nominally undoped SiC crystals were grown.

Optical evaluation of doping concentration in SiO2 …

29/9/2011· On the contrary, Boron doped samples exhibits similar k values thus there is obvious trend in αvalues (Table 2). We can find a linear relationship between sputtering power and α (Fig. 3 ). Therefore it might be possible to simply correlate α with doping concentration that is proportional to the sputtering power for B doped SiO 2 But it is not effective for P doped samples especially for

Effect of boron doping on microwave dielectric properties …

21/1/2011· Boron-doped SiC powders were synthesized from the Si/C/B system in a nitrogen atmosphere by coustion synthesis. Results showed that boron benefited the crystallization of β-SiC, and that SiC solid solution with B acceptor doping was generated in coustion process. In the frequency range of 8.2–12.4 GHz, it was found that both real part ɛ ′ and

Boron diffusion in nanocrystalline 3C-SiC. The diffusion of boron in nanocrystalline silicon carbide (nc-SiC) films with a grain size of 4-7 nm is studied using a poly-Si boron source. Diffusion is found to be much faster than in monocrystalline SiC as it takes place within the grain boundary (GB) network. Drive-in temperatures of 900-1000 C
