Outline of Final Research Achievements

We have demonstrated so far that the field-effect transistors (FET) enables electrical control of the state of matter by external voltage. On the other hand, FET should in principle enable continuous change in the number of electrons in a solid, providing a very powerful tool for developing electronic phase diagram as a function of the number of carriers. From this viewpoint, we have developed novel properties of cuprate superconductor nano-devices under electric field. Then, for La2-xCexCuO4, a representative electron-doped cuprate superconductor, we realized the insulator-to-superconductor transition by the electric-field effect, and revealed the existence of the charge-order phase in the underdoped regime from a detailed examination of the electronic phase diagram while precisely changing the number of electrons.
