N-TYPE SEMICONDUCTOR DIAMOND PRODUCING METHOD AND SEMICONDUCTOR DIAMOND

摘要

An n-type semiconductor diamond producing method, an n-type semiconductor diamond, pn-junction semiconductor diamond, a pnp-junction semiconductor diamond, an npn-junction semiconductor diamond, and a pin-junction are provided. A diamond {100} single-crystal substrate (10) is processed to form a diamond {111} surface. A diamond is epitaxially grown while the diamond {111} surface is being doped with an n-type dopant to form an n-type diamond epitaxial layer (20). Combining a thus produced n-type semiconductor diamond, a p-type semiconductor diamond, and a non-doped diamond, and using a p-type semiconductor diamond {100} single-crystal substrate, a pn-junction semiconductor diamond, a pnp-junction semiconductor diamond, an npn-junction semiconductor diamond, and a pin-junction semiconductor diamond are produced.
