  • Method of fabricating n-type semiconductor diamond, and semiconductor diamond
    Publication number: 20070111498
    Abstract: An n-type diamond epitaxial layer 20 is formed by processing a single-crystalline {100} diamond substrate 10 so as to form a {111} plane, and subsequently by causing diamond to epitaxially grow while n-doping the diamond {111} plane. Further, a combination of the n-type semiconductor diamond, p-type semiconductor diamond, and non-doped diamond, obtained in the above-described way, as well as the use of p-type single-crystalline {100} diamond substrate allow for a pn junction type, a pnp junction type, an npn junction type and a pin junction type semiconductor diamond to be obtained.
