n-type semiconductor diamond manufacturing method and a semiconductor diamond

The present invention relates to a method of manufacturing the n-type semiconductor diamond, n-type semiconductor diamond, pn junction type semiconductor diamond, pnp junction type semiconductor diamond, npn junction type semiconductor diamond, and a pin junction type semiconductor diamond. In the present invention, by processing the diamond {100} single-crystal substrate (10), a diamond {111} after the formation of the surface, the diamond while doping an n-type dopant in diamond {111} plane be epitaxially grown n-type diamond epitaxial forming a layer (20). Further, n-type semiconductor diamond and a p-type semiconductor diamond obtained as described above, and combining the non-doped diamond, by of using a p-type semiconductor diamond {100} single crystal substrate, pn junction, pnp junction type, semiconductor diamond npn junction type and the pin junction type is obtained.
