Mmetụta nke ike silicon carbide dide na PhotoDetector

Isi ike silicon silicon carbide pin diode abụwo otu n'ime ebe ndị na-egwu ebe a na-eme nchọpụta ngwa ọrụ. Otu pin diode bụ ihe dị egwu dị egwu nke Sandwiching nke Semisenductor (ma ọ bụ Semiconductor nwere obere ịta adịghị mma) n'etiti mpaghara p + mpaghara.
