| Research Abstract |
It is known to the diamond that superconductivity develops by highly-concentrated impurities addition in addition to the superior performance as the wide gap semiconductor. Aiming at the future development of the field concerned and the present defeat, I suggest surface carrier control using a huge polarization of ferroelectric (Bi,Pr)(Fe,Mn)O3(BPFM).
I confirmed good interface structure without the interdiffusion between diamond, and BPFM. In addition, I showed good ferroelectricity of BPFM. On the other hand, about movement properties of the MFIS diamond FET structure that formed a source drain, enough abnormality of the drain electric current of the class of diamond channels for the spontaneous polarization of BPFM is not accomplished to date, but think that this can be improved by the defect restraint of the diamond channel.
