Abstract

We demonstrate electrostatic control of the metal-insulator transition in the typical correlated-electron material NdNiO₃ through a large effective capacitance of the electric double layer at the electrolyte/NdNiO ₃ interface. The metal-insulator transition temperature (TMI) of NdNiO₃ is shown to decrease drastically with increasing hole concentration through the application of a negative gate voltage (V _G). The shift in TMI (Δ TMI) is larger for thinner NdNiO ₃; for VG of -2.5 V, Δ TMI of 5-nm-thick NdNiO₃ is as large as 40 K, and the resistivity change near 95 K is one order of magnitude. This study may be potentially applicable to Mott transistor devices.
