Claim Text:
1. A detection device, comprising: a SiC substrate defining a substrate surface cut from planar to about 12°; a buffer epitaxial layer on the substrate surface, wherein the buffer epitaxial layer comprises a n-type 4H—SiC epitaxial layer doped at a concentration of about 1×10 a n-type epitaxial layer on the buffer epitaxial layer, wherein the n-type epitaxial layer comprises a n-type 4H—SiC epitaxial layer doped at a concentration of about 1×10 a top contact on the n-type epitaxial layer, wherein the top contact has a thickness of about 8 nm to about 15 nm, wherein the detection device has sensitivity in an energy range of 50 eV to 10 keV.
