  author={Peter A Bryant and Annika Lohstroh and Paul J Sellin},
  journal={IEEE Transactions on Nuclear Science},
The electrical characteristics and fast neutron response of a High Temperature Chemical Vapour Deposition (HTCVD) grown semi-insulating bulk SiC wafer has been measured. Current-Voltage measurements demonstrated a low leakage current in the region of 10-10 to 10-12v A with a bulk resistivity of at least 1012-1013 Ω.cm. Alpha particle spectroscopy measurements demonstrated an electron charge collection efficiency of up to 90% with reasonable reproducibility of the acquired spectra. Evidence of… Expand

Structural Controlling of Highly-Oriented Polycrystal 3C-SiC Bulks via Halide CVD
Highly-oriented polycrystal 3C-SiC bulks were ultra-fast fabricated via halide chemical vapor deposition (CVD) using tetrachlorosilane (SiCl4) and methane (CH4) as precursors and the results showed that the growth orientation of 3C -SiC columnar grains was strongly influenced by Tdep. Expand
