For practical device applications of diamond, even higher material quality is needed, and our challenges include the reduction of defects, epitaxial film growth on large-sized wafers, and control of electrons and holes. Furthermore, regarding the confinement of electrons and holes using isotopes, the lifetime of electrons and holes inside the isotopes, recombination at the homojunction interface, and mobility of electrons and holes must be evaluated in detail, and the data will be examined whether they can effectively be used to design quantum functional devices. The technology shall be developed horizontally, such as for creating 13C quantum bits.
