Illustration of Metal-Insulator Transition in Nickelates

Caption

Materials close to a metal-insulator transition (MIT) have great potential in synaptic devices. The sketch shows the behaviour of the resistivity of NdNiO3 as a function of temperature upon changing its oxygen content:the exponent that describes the metallic state can be gradually tuned from n= 1 to n=3, tuning at the same time the resistance change at the MIT. So far reporting n different from 1 and 2 was considered “exotic”. This work shows otherwise.
