Research Abstract

We succeeded in synthesizing a stack of alternating, nano-meter thick layers of isotopically enriched^<12> C and^<13> C diamonds using microwave plasma-assisted CVD with isotopically enriched methane gases. We suggested the feasibility of synthesizing a diamond superlattice comprising very thin diamond layers whose well width is as small as 1 nm. We also found that the carriers are confined due to the band gap difference in the homojunction interface. The possibility has been raised that the confinement of phonons also occurs in the isotopic diamond superlattice. We found that, currently, isotopic diamonds have a possibility to provide an effective means for facilitating the band engineering of diamond.
